Banned And Baffled

Being banned from bird ringing other than in one's own garden is frustrating and annoying. More so when the authorities continue to allow both shooting and fishing to take place in the countryside. We are hopeful that we may be able to recommence our vital conservation work soon. 

In the meantime. A couple of recoveries of ringed birds remind us of previous ringing sessions. 

We caught and ringed Lesser Redpoll Y596566 at Oakenclough way back on 4 February 2015 as a first winter female. It certainly looked like a female and also measured at 72mm wing.  Below is the picture from that day, easily retrieved from the blog because it was the only redpoll caught. 

Lesser Redpoll - Y596566

 

“There was a slight frost with both clear skies and the radio forecast promising a sunny day ahead.  Our four hours proved to be rather slow in both activity and numbers caught whereby we speculated that birds had moved from this high ground location to more urban locations a mile or three away where the temperatures would be more to their liking. 

We caught just 25 birds, 21 new ones and 4 recaptures. New birds: 8 Blue Tit, 6 Great Tit, 3 Chaffinch and singles each of Goldfinch, Lesser Redpoll, Coal Tit and Robin. Recaptures: 2 Chaffinch and 1 each of Robin and Coal Tit.“ 

Fast forward to 26 January 2021, 5.98 years later and Y596566, the single Lesser Redpoll of 4 February 2015 was recaptured by Durham Dales Ringing Group at Rowlands Gill, Tyne and Wear, some 126 kms from Oakenclough. 

Lesser Redpoll - Oakenclough to Tyne and Wear 

 

By now and with the now mature bird, Durham Dales ringers were able to more accurately age this bird as an adult male rather than the female we supposed 5 years earlier. 

Such is the danger and associated pitfalls of trying to age and sex first winter Lesser Redpolls where it is wrong to commit a bird's age to a database unless 99% positive. Hopefully we ringers learn from our mistakes. Unless of course it was a simple data input error of “F” instead of “M”! That's our excuse and we're sticking to it. 

============================= 

Although we have been unable to continue with our wintering Project Linnet because of the virus yet another Linnet recovery has come to light. 

This one again involves the island of North Ronaldsay, Northern Isles and an old friend, a male Linnet carrying Ring Number AJD6518. We caught AJD6518 for the first time at Gulf Lane Pilling Marsh on 26 November 2018. The same bird has now been recaptured on three separate occasions at Holland House, North Ronaldsay Bird Observatory - 7 May 2019, 28 June 2019 and the latest one on May 2020. 

Linnet - North Ronaldsay to Pilling 

Where this individual has been during the winter of 2020 is anyone guess but we rather hope it came back to Lancashire again, even though we were unable to prove the likelihood when bird ringing became verboten. 

After this latest information about Linnets' status on North Ronaldsay I made contact with George Gay who has the privilege of a working life on this outpost of bird migration. 

George - “The Linnets on the island leave over the winter and usually return sometime in March in dribs and drabs.  Holland is not only a roost site but their main breeding site on the island. Since 1987 we have ringed just over 7000 Linnets here but they haven't bred until fairly recently and have largely replaced Twite as a breeder on the island. 

Holland is the main site but birds do breed elsewhere on the island with Ancum Willows probably being the next most likely spot to find breeding birds. They've been on a steady increase since the late 90's to early 2000's and now roost flocks can easily reach 300-400 birds post breeding.” 

Linnets

The information above mirrors the summaries of the Linnets' status in both the BTO Migration Atlas 2002 and the BTO Bird Atlas of 2013, both of which tell of the Linnets' colonisation of the Northern Isles of Scotland during its simultaneous decline as an English farmland species. 

Two other records also show our now regular Lancashire/Northern Isles connections. 

Ring number AYD5167 was ringed as a post breeding individual at Holland House, North Ronaldsay on 8 September 2018, a rather large juvenile male of wing length 84mm. We recaptured the same bird at Gulf Lane, Pilling, Lancashire on 24 December 2018. Here is a clear case of juvenile dispersal/migration. 

The above correspond to yet another Linnet that spent time at our winter set aside of Gulf Lane. Z722984 was ringed as a nestling of 6 siblings at Scousburgh, Shetland, 14 June 2016 and later recaptured at Gulf Lane, Pilling on 24 October 2016 - A juvenile heading south-west to spend the winter in England. This is more support for the idea about the origins of many Linnets that flock to spend the winter in the area of Pilling and Cockerham, the same birds that then depart in March to head north to Scotland. 

Linnets

The value of bird seed and cover crops in many English locations becomes apparent as does the need for constant monitoring to spot changes taking place in the countryside.  

Linnets

Come on Boris, Natural England and BTO, give us our ringing back. We much prefer it to shooting or fishing. Don't you?

============================= 

Back home in the garden 2020/2021 has proved a peculiar winter with almost zero bird activity apart from the occasional Goldfinch and Blackbird. 

Goldfinch

Perhaps the continuous unsettled weather has caused birds to move elsewhere to seek food. The grass is squelchy through the endless rain with no opportunity for it to dry out. Days of sunshine are rare with the chances of catching a few birds remote. 

Stay tuned friends. We may be banned but we haven't given up hope of a return to ringing soon.

 

Nature Calls

Three a.m. and nature called. Later life has so many advantages but one or two drawbacks. With the alarm set for 0520 thoughts turned to the ringing session ahead and I knew that sleep would not return. At 0500 I switched the alarm off but took great care not to wake Sleeping Beauty. 

Closer to destination Oakenclough interminable Long Lane rose to 700 above sea level as the black morning turned suddenly to gloomy hill mist and low cloud. Not exactly what the ringer ordered; Andy and I had missed another two and a half weeks of ringing due to unremitting wind and rain sweeping in from The Atlantic. 

Our last visit had been on  6 November 2020.  Nevertheless it felt good to be out again and where if the ringing was quiet, we could for sure put the world to rights via a cup of coffee, a natter and a few choice words. 

The mist cleared, reappeared and then cleared again with barely a hint of the promised sun. What a strange sort of morning with few birds on the move save for a couple of flocks of Redwings, separate groups of fifteen and a forty, plus a few stragglers. Otherwise, 15-20 Chaffinch, a Kestrel gliding through the mist and the usual suspects at George’s bird feeders 30 yards away. 

Just 10 birds caught - 3 Goldfinch, 3 Blue Tit, 2 Coal Tit and 2 Redwing. You can bet things are pretty quiet when a ringer posts a Blue Tit. 

Goldfinch - Carduelis carduelis

 

Redwing - Turdus iliacus

 

Blue Tit - Cyanistes caeruleus

Unlike recent weeks the weather looks fairly settled for a day or two so there may be chance to get some ringing and/or birding in. For tomorrow we have planned a visit to the Linnet catching site of recent years at Gulf Lane, Cockerham. We hope to clear an area of the now defunct crop to instead establish a whoosh netting area and bait it with a rape seed, niger and millet mix. 

So far this autumn and winter there is no sign of a Linnet flock and despite a number of drop-in visits, the site has very few birds. Regular readers of this blog will know of our successes in previous years by  establishing that many of the wintering Linnets in our local area originate from Scotland. Our total is 741 Linnet captures from 2016 to 2020. 

Linnets - Carduelis cannabina

Colder temperatures in January, February and March 2021 may see an influx of such individuals again and open up the possibility of catching other species like Chaffinch, Reed Bunting, Skylark and Stonechat. 

We don’t succumb so easily to quiet days; they are part and parcel of a day in the great outdoors. What would we do otherwise? Watch daytime TV for a daily dose of brainwashing?

Food For Thought

Saturday was cool, blustery and showery just like the week gone by when there was no birding and no ringing. Hopefully the showers would not turn to rain and I could at least get a little birding done. 

With so few Swallows of late one could be forgiven for thinking they had all left for Africa with a cold arctic wind up their backsides. Not so, because at Conder Pool many hundreds of mainly Swallows converged on the morning hatch of insects. My approximate count was of 450 Swallows, 40 Sand Martins and 30 House Martins which swarmed along the north bank in the lee of the hedgerow, across the water and over the island’s vegetation for two hours or more. 

This feeding frenzy is a regular autumn occurrence now the waterside hedgerow is mature enough to hold large numbers of midge and mosquito type insects - little critters that we call ‘gnats’ or ‘flies’, some of which are actually mosquitoes. 

Yes, I heard them this morning and “mozzies” are definitely in Lancashire. I’ve seen, heard and then squashed enough mosquitoes in Africa, Asia and the Med to recognise the sound of their landing approach.  It was so satisfying to hear the snap of the Swallows’ bills as another enemy bit the dust a yard from my face and to watch as thousands more perished in the birds’ onslaught. 

Swallow

 

Buoyed up by the merciless carnage I periodically turned my attention to other birds present and their less obvious need to eat at the pace of early morning hirundines, creatures who spend dark nights balancing on draughty reed stems. 

In 1981 in North Lancashire I saw my first Little Egret, a species that very quickly found a niche, swelled in numbers and is now so ubiquitous that it can be seen 365 days of the year, winter, spring, autumn and summer.  This species should by now be renamed as Common Egret, rather like Common Man - the average citizen, as distinct from the social, political or cultural elite. 

These delicate little diners eat mainly fish, with at times amphibians, small reptiles, mammals, crustaceans, molluscs, insects, spiders and worms. There were three egrets today, and as I watched they seemed to prefer the tiny fish that inhabit the pool, but mostly the prey would be swallowed in the blink of an eye before it could be named. 

Eight Little Grebes took their prey under water but when one emerged carrying a ready meal it was invariably the same minnow the egrets take. 

 “Minnow is the common name for a number of species of small freshwater fish, belonging to several genera of the family Cyprinidae.” 

Little Egret

 

To their credit, our local Mute Swans appear to be vegetarian. But, like many a “veggie” they occasionally, and entirely by accident, when no one is looking, have been known to sneak the odd meaty mollusc or worm. 

Mute Swan

 

Waders and wildfowl were of the usual variety and numbers with 40 Lapwing, 20 Redshank, 15 Curlew, 3 Common Sandpiper, 1 Greenshank, 6 Tufted Duck and 40 Teal. 

Those Curlews can be missed when they feed amongst this year’s grasses, grown tall and lush in record rains. I suspect that beneath the puddles lay soft soil containing goodies that curved, probing bills could easily find.

It was good to see a flock of 50/60 Goldfinches feeding in both the marsh grass and on the dandelions and thistles. Good to see because Goldfinches have been strangely absent from my own garden for weeks, not unexpected when there is much natural food about. 

Goldfinch

That’s all for now.  I’m off to prepare a chicken tandoori with salad. There's more food for thought soon on Another Bird Blog. 

 

Business As Usual

Three mornings in the same week must be some sort of record for Oakenclough. The forecast of zero wind and a dry morning dictated a start at 0600 for Andy, Bryan and yours truly. Off we go again – Three Go Ringing 

Moody Morning 

Although the clouds looked threatening, showers stayed away, the sun shone briefly and we caught migrants in the way of more Willow Warblers, Blackcaps, and yet another Garden Warbler. Towards the end we had our first Tree Pipit of the autumn. 

We packed in soon after 1100 with 43 birds of 13 species as follows :- 7 Willow Warbler, 6 Chaffinch, 6 Coal Tit, 6 Blue Tit, 4 Blackcap, 4 Goldcrest, 2 Goldfinch, 2 Treecreeper, 2 Great Tit and one each of Dunnock, Robin, Garden Warbler and Tree Pipit. 

The titmice numbers were unusually high because the normally well-stocked feeders at the house just thirty yards away were empty this morning. Earlier in the week we noted how local Chaffinches, Blue Tits, Great Tits and Coal Tits enjoyed fulsome meals as the container levels dropped. Only today at the sight of empty feeders did those birds stray into mist nets 50 yards away from their regular snacks. 

Although it is very difficult to see in the picture, the Tree Pipit had already started its post juvenile moult in the crown feathers. 

Tree Pipit 

Treecreepers often travel with tits in search of food. We seldom catch one, never mind two in a morning or three in a week as we have this time. The one below is a juvenile. 

Treecreeper 

A juvenile Blackcap shows how post-juvenile moult makes the sex easy to determine as the summer progresses. 

Blackcap 

juvenile Robin  

A wing length of 81mm and the sheer bulk of this Goldfinchs’ bill strongly suggest a male even though it does not look like one just yet. 

Goldfinch 

Today’s seven Willow Warblers brought our total to 39 "WILWA" captures for the month of July. 

Willow Warbler 

Looks like we are back to normal tomorrow and over the weekend with yet more rain. Fortunately we made hay while the sun shone with 156 birds caught here in the month of July.  

Back soon with Another Bird Blog. Stay as normal as possible my friends. 

But don't go shopping to The High Street, it ain't there. Boris just killed it.

Too Good To Be True

After another week of rain and rubbish weather we hoped that today’s forecast of a decent morning would be accurate. 

On the drive towards Oakenclough a hint of sun broke the early clouds. At 0630 roadside trees hardly stirred. This was all too good to be true. And so it proved.  For the next four hours Andy and I dodged periodic drizzle and showers that blew in from the west until we packed in at 1030 when light rain turned to a heavy wetting shower. 

Had the sun stayed around longer we felt sure that our catch would have been higher as despite the cool showers and grey skies, there seemed to be good numbers of birds moving through the area. Between the drizzly showers came post-fledging parties of Nuthatch, Chaffinches, titmice and Swallows. One of these moments brought in a Hobby that gave a rapid fly past before heading south east and out of sight. A birder who lives not far away reports seeing a Hobby every day of the week. 

Given the stop-start nature of proceedings we were quite pleased to finish with 28 birds of 13 species – 24 juvenile birds of the year and 4 adults - 8 Willow Warbler, 3 Chaffinch, 3 Coal Tit, 2 Chiffchaff, 2 Blackcap, 2 Treecreeper, 2 Great Tit and singles of Goldfinch, Robin, Wren, Blue Tit, Goldcrest and Garden Warbler. 

Pictures below - all taken at ISO800/1600 in poor light yet again. Whatever happened to summer?

Note how the outline shape of the Chiffchaff wing differs from the Willow Warbler. The Chiffchaff wing is shorter and rounder with primaries 3,4 and 5 of similar length. Primaries 3 and 4 of a Willow Warbler wing are longer than primary number 5.

The sixth primary feather of the Chiffchaff is partially emarginated whereas the equivalent feather of the Willow Warbler is not emarginated.

The differences are easier to see from the drawings in my 1984 dog-eared edition of "Svensson". But the facts remain the same in 2020.

Garden Top Ten

Thanks to the Wuhan Flu and house arrest it seems we are all to become garden birdwatchers until further notice. 

Just in time then to read of the latest results from the RSPB's Big Garden Birdwatch, an event held over the weekend of 25-27 January 2020 when nearly half a million people counted almost eight million birds. It made this year’s Birdwatch one of the biggest ever. 

The RSPB even produced a Top Ten, a list that depending upon a particular location may not equate to all gardens but represents a combined average result from the whole of England, Scotland, Ireland and Wales. 

Here they are in one to ten order; a list to bring tears to eyes of WhatsApp “bird news” groups. Not a single “scarce or rare” among them. In the archives of Another Bird Blog I found a picture for each of the species, useful ID pointers for those who have little or no time for common birds. 

The figure in brackets is a guesstimate of the top ten in my own garden for an average January day. In our garden, Magpie is replaced by Dunnock, a much nicer prospect. Magpies aren’t around because I chase them off as soon as they appear:

1. House Sparrow (10)
2. Starling (8)
3. Blue Tit (5)
4. Woodpigeon (2)
5. Blackbird (3)
6. Goldfinch (1)
7. Great Tit (4)
8. Robin (6)
9. Long-tailed Tit (9)
10. Magpie (0)
10. Dunnock

House Sparrow 

Starling 

Blue Tit 

Woodpigeon

Blackbird

Goldfinch 

Great Tit 

Robin

Long-tailed Tit

Dunnock

The RSPB Top Ten of the changes little from 2019, with the top three birds the same as last year. Again, the Number One spot is taken by the House Sparrow, making it first for seventeen years running. Meanwhile the House Sparrow is nowadays an uncommon visitor to our ample sized semi-rural garden. Here the House Sparrow struggles to even hit the charts, despite the RSPB report suggesting that their numbers appear to have increased by 10% in the last ten years. 

The RSPB detect movement at fourth and fifth, with the Woodpigeon moving up to four and, last year’s number four the Blackbird falling to five. This is not surprising given the highly adaptive pigeon’s abundance here in Stalmine that gives the species an easy runner-up place in our garden list. This commonality is explained by a nearby mix of farmland, many trees, thick hedgerows, tolerant residents and few shooters. 

Small birds like Long-tailed Tits (up by 14% on 2019), Wrens (up 13%) and Coal Tits (up 10%) counted well during a mild, wet winter that came with very few frosts and little snow. The 14% for Long-tailed Tits also accounts for it remaining high on our local list as a past breeding species in the berberis bush; and a regular visitor likely to nest again. 

The report showed that Chaffinch dropped from the top ten down to number 11. This placing reflects very recent news that this once abundant farmland bird is the latest species in trouble through agricultural changes and over-building on green land and woodland edge. Sadly the Chaffinch is no longer a regular in our own garden. 

Losers out this time included Song Thrush way down at 20th in 2020, seen in just 9% of all gardens. Compare this to earlier Big Garden Birdwatches of 1979 -2009 when the Song Thrush made a top ten appearance in every year. In our garden, the once common Song Thrush is both "scarce and rare".  

It's a surprise the Goldfinch doesn’t even make the RSPB top five when here in Stalmine it is far and away the most common garden bird at any time of year. Perhaps the Goldfinch is not yet a city bird where many of the Big Garden Birdwatchers reside? 

Greenfinch is another big loser over the span of the Big Garden Birdwatch, a reflection of a major nationwide decline in its population. It came in at 18th and was seen in just 14% of gardens, this itself a worrying drop of 8% on 2019. We have a pair of Greenfinches in the garden so we count ourselves rather lucky in many ways. 

And the cherry blossom smells just wonderful.

Stalmine

At least the good weather means we don’t sit in in the house and watch TV.  I’m told there are still people who pay a TV Licence fee for the privilege of having their intelligence insulted!   

Meanwhile, the Government is in a “damned if they do, damned if they don’t” situation.  A relaxation of the lockdown advice will be pounced on by TV and newspaper media and used to whip up even more public hysteria.  The effect this media-generated madness is having on an already browbeaten population has been leapt upon as an excuse for a monumental power grab by the illiberal left, forever eager to bring down an elected Government.  

Back soon with Another Bird Blog and tales of The Great Escape.

Back To The Future

Get used to it you birders. This is the dystopian, authoritarian future. The current lockdown is just a dress rehearsal for the real thing of the not too distant future. 

The Department for Transport has launched a consultation paper which calls for a major move from cars into cycling, walking and buses, but has told few people about it. 

The paper, Decarbonising Transport: Setting the Challenge, crept out on March 26. Citing the Government’s 2050 net-zero greenhouse-gas emissions target, Transport Secretary Grant Shapps writes of a vision where - “Public transport and active travel will be the natural first choice for our daily activities. We will use our cars less and be able to rely on a convenient, cost-effective and coherent public transport network.” 

He adds: “From motorcycles to HGVs, all road vehicles will be zero emission and technological advances . . . will change the way vehicles are used.” 

How will the reduction in private transport be achieved? By making private cars too expensive for ordinary people? Rationing cars to one per family? Rationing mileage  by road charging? Or maybe we will end up with scenes observed this week, where the authorities allow car travel for specific purposes only? Or more worryingly, cars for elite sections of society only - politicians by any chance? 

Animal Farm

Fortunately, happier thoughts are to be found in Another Bird Blog archives from December 2014 when I asked the question “Do Birds Smell?”.

==========

It’s a question I asked myself a number of years ago when noting how long it took for birds to discover new sources of food, in particular the introduction of bird feeders where none had been used previously. 

Birds were always thought to have a very poor sense of smell. But most vultures and many scavenging seabirds locate their food by smell. Any birder who has been on a pelagic trip to see seabirds up close will be familiar with the practice of chucking overboard buckets of “chum” or “rubby-dubby”, to lure shearwaters and petrels close to the boat. 

Manx Shearwater

Wilson's Storm Petrel

Scientists believe that other birds, e.g. homing pigeons, may use familiar odours in finding their way home or use their sense of smell during migratory journeys. Think about the various odours given off to overflying birds by different places, e.g. pine forest or ancient deciduous woodland, saline or fresh water, the urban jungle or the countryside. 

Egyptian Vulture 

A recent Dutch study determined that Great Tits found and located apple trees with winter moth infestations and big concentrations of caterpillar larvae by smell rather than sight. Tit species eat large numbers of insect larvae particularly during their breeding seasons when they feed them to their young, timing their breeding to do so. Trees benefit from the protection offered by birds removing larvae that would otherwise go on to eat the leaves and perhaps impact on tree growth and productivity 

Great Tit 

The Dutch experiments were designed to remove other possible ways in which the Great Tits might detect the winter moth larvae. The researchers removed the caterpillars, removed leaves with holes and even took away signs of ‘caterpillar poo’, ensuring no visual clues were left for the birds to locate the infested trees. Despite these measures the Great Tits repeatedly found the trees with larvae infestations. 

The results were clear, even when they couldn’t see the trees, the Great Tits homed in on trees with winter moth infestations when they could smell them. The researchers believe the trees gave off chemicals which birds can detect by smell to alert them to infestation. It has long been known that many plants attract insects using smells and benefit from the relationships as a result, but this is the first time they have been shown to attract birds in the same way. 

More research is needed to determine which chemicals are involved but infested trees were found to release more of a chemical responsible for the “green” smell of apples. 

Most bird feeders use metal/plastic tubes or wire mesh to make the food highly visible to birds and we naturally assume that birds start to use our bird feeders because they locate food via their keen eyesight. My new niger seed feeders arrived today, replacements for ones recently stolen from a ringing site. At first glance the design looks improbable and unlikely to work as the feeding holes are tiny. When the stainless steel cylinder is filled with niger, the seed is virtually invisible with just the tiniest point of an individual seed poking through a hole. 

Bird Feeders 

Nevertheless I experimented with this design of feeder a number of years ago and found them to be highly successful in attracting Goldfinches, Siskins and Lesser Redpolls very quickly and I attributed some of this to the birds’ ability to smell the seed. 

Goldfinches 

Here’s an experiment anyone can try at home. Buy a sealed bag of niger seed, open the bag and stick your nose in it. Then inhale and enjoy the sweet, oily, nutty fragrance which brings in those Goldfinches 

There’s is no doubt in my mind that birds and in particular Goldfinches have well developed olfactory senses, probably as good as our own. 

Now you must excuse me. From the kitchen I detect the unmistakable aroma of a tandoori chicken sizzling on the grill. 

Tandoori Chicken

I'm ready for a bite to eat. Back soon with more tasty morsels from the past.
