Double Whammy

There’s a double blow to our ringing plans this weekend. Number One is the weather with a Red weather warning of severe winds up to 70mph over northern Britain as Storm Arwen passes over in a north to south direction. Sat here in my office there’s a hoolie blowing and I’m not for going anywhere until Monday when the winds should ease. 

Wednesday saw another visit to Project Linnet where Catch of the Day was that extreme rarity - a Song Thrush. After a little levelling off in recent years the graph seems to be heading in a downward direction again via “a rapid decline in England” - BTO Bird Trends. 

For what it’s worth the decline in this part of Lancashire seems especially marked where the Song Thrush is no longer a garden bird and is one that receives barely a mention on local bird news Internet sites. Our own catches of Song Thrushes number so few that catching a Song Thrush becomes a Red Letter Day.

Song Thrush 

In addition to the single Song Thrush we caught 1 Redwing, 2 “continental” Blackbirds, 2 Blue Tit, 1 Greenfinch, 1 Robin and added another seven Linnets to our totals.

Just as were looked forward to better weather next week, Friday morning brought unwelcome Blow Number Two. 

“Dear Philip” 

“Avian influenza H5N1 (pathogenicity to be confirmed) has been found in a premises near Poulton le Fylde, Wyre, Lancashire. A 3km and 10km Control Zone has been put in place around the premises. Please see the map here for more information (search on SD3748). 

You are being notified as we can see you, or your ringing group, have either submitted ringing records from close to the outbreak in recent years or your postal address is within the area. 

Effective immediately, as a precaution, the following measures apply: All ringing is suspended within the 10 km Control Zone as outlined on the map until further notice. 

We will inform you by email when ringing can recommence and we will be monitoring the situation during the BTO Christmas period.” 

Avian Flu Hotspot

 

A couple of our local ringing sites fall into the exclusion zone, another unwanted blow to our commitment to local bird ringing, activities that monitor bird populations for the benefit of society as a whole. Project Linnet (and farmland birds) is now on hold until sometime in 2022. 

This latest episode is the third recorded outbreak of bird flu at the same Preesall/Pilling premises https://anotherbirdblog.blogspot.com/2017/01/a-touch-of-flu.html 

Once again in 2021 the avian virus has been found where Pheasants, Red-legged Partridge and Mallards are reared in captivity so as to be released into the countryside for shooting. This is a subject covered many times here on Another Bird Blog, in the birding press on a regular basis and in National newspapers on a number of occasions. As ever there is no interest from the UK Government or other parties to put a stop to an archaic practice that has such a devastating impact upon native species. 

The BTO Atlas of 2013 tells me that the numbers of captive-bred Pheasants released into the wild has increased fivefold since the early 1960s to around 35 million birds annually. Some 15 million Pheasant are shot annually. 

Captive Pheasant rearing

“High densities of Pheasants potentially have negative effects on native species, but these have been poorly studied. Indirect effects possibly include modification of the structure of the field layer, the spread of disease and parasites and competition for food. Recent research indicates that infection with caecal nematodes from farm-reared Pheasants may be contributing to the decline of Grey Partridge.” 

Grey Partridge

When I watch hordes of young Pheasants thundering through late summer fields and woodland edge there is no doubt in my mind that their effect on the environment is wholly negative. 

The BTO Atlas also states that there has been a 91% population decline of Grey Partridge in the UK between 1967-2010, during the Breeding Atlas of 1968-72 and the Breeding Atlas of 1988-91. 

“Local extinctions may be masked in some areas by the release of captive-bred birds onto shooting estates: about 100,000 captive-reared Grey Partridges are released in Britain each year”. The Atlas gives no figures on the number of captive-bred birds subsequently shot for sport; neither does it give any indication of how any surviving birds impact upon any truly wild Grey Partridge population. 

Given that the Grey Partridge is in any case a secretive and difficult species to study, any such investigation would by now be almost impossible to conduct. 

The problem is further complicated by the release into the same environment of Red-legged Partridge, a picture I know only too well from local farms. 

Red=legged Partridge

 

"As more farms diversify into shooting, the number of Red-legged Partridges released has increased and this is illustrated by the National Gamebag Census, where numbers shot quadrupled between 1990 and 2005 (Game & Wildlife Conservation Trust 2013). It is estimated that 6.5 million partridges (Grey and Red-legged) were released across the UK in 2004, and 2.6 million were shot. There has been little research on the impacts of released birds on native species, but there is some evidence that shooting operations based on large-scale releases of Red-legged Partridges could be implicated in local extinctions of Grey Partridges.” 

Red-legged Partridge

To my unscientific but daily birding eyes that last sentence would seem to be a gross understatement. 

At the end of the day there is one conclusion to be drawn from this now familiar, sorry story. 

Nothing will change - just Follow The Money.

Making It Count

“Don’t count the days. Make the days count” - a quote from the greatest boxer of all time Muhammad Ali. 

On that basis I rose at the unearthly hour of 0530 on Friday to meet up with Andy out Pilling way to once again set up mist nets in the half-light of 3° where cold fingers fought to stay warm.  With no time for chitchat our priority was to set nets in readiness for early birds in search of a worm or two, hopefully Redwings. As the morning progressed we expected to add more species and numbers. 

Although we have both seen and caught numbers of Redwings this autumn, the strange weather of the last three weeks has seen very few Fieldfares to accompany their cousins. The two thrushes often arrive together in mixed flocks of tens, dozens, hundreds or even thousands, but not this year. Perhaps Friday would see both arrive as dawn broke or soon after? 

There were no Fieldfares again so we made do with three Redwings that found the net in the dark. Those were the only ones we caught out of 40+ that flew over in tiny groups in three hours and more. 

The morning continued with a light drizzle out of the 100% grey cloud and poor visibility, murk that hung around for quite a while and prevented us from any useful birding. The light was so poor that my camera stayed in the car, these pictures from previous days.

The most notable thing about Friday morning was how the highly mobile Linnets reached approximately 200/250 individuals, a number reflected in our catch of 21. This brings the total of Linnets ringed here this autumn/winter period to 192 - with zero recaptures. If only we could persuade more NW ringers to target Linnets we might together discover more about this Red Listed species. 

New birds caught: 21 Linnet, 3 Redwing, 2 Greenfinch, 1 Wren, 1 Long-tailed Tit, 1 Blue Tit and 1 Reed Bunting.

News arrived of a Lesser Redpoll, Ring number AKE3924, a second year female we ringed up at Oakenclough back on 19 March 2020. 

AKE3924 was recaptured over the Pennine Hills by other ringers in Spennithorne, North Yorkshire on 20 October 2021, a duration of 586 days and a distance of 73 km. 

This is another between years Lesser Redpoll recovery that tells us little except that both dates coincide with known migration times of Lesser Redpolls and also their north/south and south/north movements in spring/autumn.

We live to ring another day but probably not this weekend when the weather again turns unfriendly. 

The whole of next week looks reasonable in which to make our bird ringing and bird observations contribute to the wider picture. Log in then to Another Bird Blog to see how we do.

 

Starting Afresh

This last two or three weeks was possibly the worst cycle of rain & wind weather systems I have experienced in my years of being a birder, bird ringer and weather watcher. 

Every day became a “no go” until a brief respite on Tuesday took me to our Pilling ringing site to assess the damage. Fortunately things were not as bad as feared once the still flooded track was negotiated by avoiding soft spots where the car might sink. Puddled net rides might dry out overnight given their open situation, while ropes left in situ were still visible if soaked and wind-blown wayward. 

By a miracle and in the few hours of dry with glimpses of sun, it seemed a few birds had returned or perhaps never left; alongside the fence flew three Stonechats and in the trees Reed Buntings, Linnets, Chaffinches, Greenfinches and Redwings. A Buzzard mewed in protest as crows gave chase and Skylarks flitted overhead. 

On the pool with ducks a single Gadwall faked being a Mallard and then drifted out of sight. I dreamt I heard a Water Rail.

All was well for new a beginning on Wednesday, perhaps Thursday, and even Friday. 

“Now then Mr Slade don’t get carried away. It can't last”, came the weatherman’s voice. 

I arranged to meet Andy at 0645, a new time now that clocks are also back to a normal winter.  

We rather hoped the Stonechats might be around to spice up the morning but there was no sign of any Stonechats, just the expected species list dominated by approximately 120 Linnets in several small parties that came and went through our four hours. The Stonechats were a “one day wonder” and almost certainly moved on during the overnight clear skies of Tuesday/Wednesday. 

We caught 21 new birds – 7 Long-tailed Tit, 5 Linnet, 4 Greenfinch, 2 Redwing, 1 Robin, 1 Blue Tit and yet another Chiffchaff.

Birds noted in between our ringing, mostly approximate numbers: 120+ Linnet, 25 Greenfinch, 18 Redwing, 4 Skylark, 2 Chaffinch, 2 Reed Bunting, 10 Little Egret, 1 Buzzard, 1 Kestrel, 1 Sparrowhawk. 

The forecast is OK for tomorrow, maybe even better by way of less of a breeze and more sun. We arranged to meet up again for another go. 

What's that saying? Make hay etc, etc.

Stick Or Twist

There was a 6° and cold but clear start to the latest ringing session at Cockerham. I’d met Andy on site at 0730 and within minutes we had a few nets up. 

Linnets began to arrive but in less numbers than recent weeks. Our best Linnet count today was 130+. As the morning progressed we wondered if constant attention from two, possibly three, or even four Sparrowhawks big and small had caused the previously large Linnet flock to fragment into the smaller groups we saw. 

These Sparrowhawks must find the Linnets a relatively easy catch as they appeared a number of times and used various methods by which to catch Linnets, succeeding just once. In comparison the hawks appeared to ignore the flocks of Starlings we saw throughout the morning. 

Sparrowhawk

Less Linnets round and about meant a smaller catch of that species, balanced out by more Greenfinches, a couple of Reed Buntings and a Redwing. 

Totals caught - 23 birds of 5 species -13 Greenfinch, 6 Linnet, 2 Reed Bunting, 1 Redwing, 1 Great Tit.

Quite suddenly Lapwings are back in our area in large numbers. Many flew over the ringing site this morning heading for nearby fields. And then on the way back home and through Pilling at about 1115 there seemed to be rather a lot of Lapwings in a roadside field. I stopped for a closer look and counted 1700! 

There were piles of Starlings too and although I was more interested in the Lapwings and whether Golden Plovers were in the mix, I knew that both Starlings and Lapwings had recently arrived from similar areas of Europe and that hereabouts it's not unusual to see Starlings feeding alongside Lapwings. 

British Lapwings are mostly resident, but some migrate westwards to Ireland and others fly south to France and Spain. Any remaining winter population is increased to about 2 million by migrant Lapwings from continental Europe. 

From late summer, migrant Starlings from as far as Scandinavia, the Baltic States, the Low Countries, Germany, Poland and Russia join our resident Starlings to make enormous daytime flocks and to form huge night-time roosts.

Lapwings

 

At Gulf Lane, our usual catch site for Linnets there was a flock of 50+ in a very similar seed plot to the morning's site not too far away and where we have caught 144 Linnets so far this autumn. 

Now we are left in a quandary with a wealth of places in which to catch Linnets. Do we stick where we are or move soon to tried and trusted Gulf Lane and its 819 Linnets over recent winters? 

Answers please on a postcard to Another Bird Blog...........

Redwings Aplenty

We swop and change our ringing sessions according to available bodies, the weather, and the theory that too many or too few days at the same location is not normally a good idea. Hence, Wednesday saw three ringers, Andy, Bryan and me back at Oakenclough, 15 miles from the coast, 700 metres above sea level at our autumnal site for catching Redwings and other migrant birds. 

We have learned that when weather conditions are suitable many bird species use this edge of the Pennine Hills as a part of their migration route, east to west/west to east or north to south/south to north. Very often the directions of travel change mid-stream or are impossible to decipher if birds disappear from view by distance or landscape. 

Examples of visible migration become especially evident during October when it is possible to witness nocturnal and diurnal migration of large numbers of northern thrushes like Redwing, Fieldfare, Blackbird, Song Thrush and Mistle Thrush. The most numerous of this group are Redwings and Fieldfares, species that migrate on any given day but whose migration is wholly unpredictable and may be as small as a few dozen individuals, or on occasions many thousands over the course of a single morning. 

The forecast for Wednesday of brightness, zero rain and a 8/10 mph breeze looked almost perfect so we arranged to meet at 0645, just before dawn. The drive up to Oakenclough is a steady climb in third gear so as to maintain a respectable speed while watching for unpredictable deer and roadside pheasants that can dent a moving car. Gaining elevation and ever closer to my destination the low cloud turned to mizzle & drizzle as visibility dropped to 20 yards. Parking up there was a 15 mph wind rattling overhead trees and the weather forecaster was treated to yet another expletive. 

We concurred. If Redwings had been on the move during the night and into morning they could well be around despite the unwelcoming weather, so we set nets and hoped for the best. 

Amazingly and even in these poor conditions, Redwings arrived. They came slowly at first, with four Redwings on the first look at the nets. And then more of them, and also other species as the morning wore on. 

Redwing

About 0920 and without warning a flock of almost a thousand Redwings arrived from the east and circled around for a few minutes before flying west. The same thing happened again later as at least two more large contingents of several hundred Redwings arrived and left to the west, as did smaller parties of tens and twenties, sometimes mixing with flocks of finches disturbed from the treetops by the swirling Redwings above them.  

Cloud and drizzle encircled us north, south, east and west as it ebbed and flowed, appearing to ease off before starting up again, but all the time we added to the catch. At 1030 real rain arrived to replace the mizzle as an unwelcome flock of 19 titmice, blues, coals, longtails and creepers found a net – time to pack in after almost four hours of intensive work. 

We finished with a catch of 54 birds - 26 Redwing, 4 Chaffinch, 3 Goldfinch, 2 Lesser Redpoll, 12 Blue Tit, 2 Coal Tit, 2 Treecreeper, 2 Long-tailed Tit and 1 Goldcrest.

We totted up the sightings – mostly approximate taking into account the poor visibility - 2500 Redwing, 40 Lesser Redpoll, 40 Jackdaw, 25 Goldfinch, 25 Chaffinch 2 Siskin, 1 Mistle Thrush, 1 Chiffchaff, 1 Kestrel.

It had been a good morning. It’s not everyone who sees 2500 Redwings in a single morning or witnesses at first hand the magic of bird migration. 

More soon from Another Bird Blog. Don't go away.

Better Luck Next Time

Friday was on flat coastal fields at Cockerham, just south of Lancaster. Saturday a change of scene in the hills at Oakencolugh on the edge of Bowland Forest, the two places 15 miles apart and a good way from each other in their respective landscapes and the species they support. 

We have a number of ringing sites from which to choose and to juggle for maximum effort and a concentrated catch but it’s far from an exact science where birds and the weather pool their resources and frustrate our best. The forecast for Saturday was reasonable enough at 8 mph and dry until early afternoon when rain would move in from the west. 

The journey across the early morning moss roads was enlivened by a Tawny Owl that flew across the road ahead and then not 200 yards more, a Barn Owl alongside the road. As a strictly nocturnal animal local Tawny Owls are rarely seen in comparison to the Barn Owls that frequent. 

Barn Owl

 

This was a good start to anyone’s day and heightened expectations when Andy and I met at dawn in in readiness for the arrival of early October Redwings. To catch the first ones of the autumn always brings a thrill. 

The potential problem was that even at this time of the morning the breeze was close to 15 mph and as soon as it became light we could see from our elevation that a good deal of cloud sat over the Fylde coast to the west and into Morecambe Bay to the north. The rain was on the way three or four hours before the expert predictions of Friday evening and even Saturday morning.  

West Lancashire

We caught the "first" Redwing at about 0745 and then no more, even though in the next three hours we saw approximately 90 Redwings in small groups, most of them arriving from east or south east and then flying west without stopping. 

Redwing

A niggling wind and increasing cloud to 100% did little to help our cause as small flocks of finches, mainly Chaffinches and Goldfinches flew from north to south in opposite conduits to Redwings. The light was so poor that many a finch could be positively identified by close call only. We settled on roundish figures of 100 Chaffinch, 35 Goldfinch, one or two each of Siskin & Lesser Redpoll and 3 Pied Wagtail. 

Lesser Redpoll

 

The Redpoll and the Redwing were just reward for our efforts, the remaining Wren, Blue Tit and Great Tit (2) a somewhat embarrassing result. 

Drizzle rolled in slowly at first until 0945 when it became persistent. The wind dropped to near zero but too late and it was time to pack in and hope for better luck next time. 

 

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?

Thrush Time

There was a heavy frost this morning with the temperature at minus 4C when I cleared the car windows but then struggled to open the frozen solid doors. 

At those temperatures I decided to give ringing a miss but stopped at Gulf Lane on the corner of the A588 to empty a bucket of seed and to count the Linnets ready for milder days. There seemed to be about 70 Linnets, a few Chaffinches and the usual Little Egret in the adjacent ditch. 

Linnets 

Goodness knows why but I followed the lane around the edge of Cockerham Moss, farmland where crops once grew and where winter stubble and unpicked potatoes provided boundless food for birds like Tree Sparrow, Skylark, Chaffinch, Yellowhammer and Corn Bunting. Nowadays “Moss Edge” is one of the worst examples of farming monoculture I know; a bird free desert where the only crop is silage grass that serves to fatten animals until they’re ready for slaughter. 

Cockerham Moss 

Cockerham Moss 

I re-joined the A588 half a mile from Gulf Lane having seen absolutely zero of note around Moss Edge and then turned right towards Conder and Glasson. 

Conder Green seems not to have recovered from its expert makeover of last year and although it is winter there are few birds to be seen. While 90 Teal, 40 Wigeon, 4 Little Grebe and 2 Snipe provided the numbers other waders proved scarce. A Kingfisher provided a literal splash of colour as it dived into the icy water from the sluice wall. 

Kingfisher 

The dry summer of 2019 gave way to a bumper crop of hawthorn and other berries. In some years berries, mainly hawthorn, get stripped quite quickly by incoming migrant thrushes. This year the countrywide crop is so big that it is lasting longer and may be responsible for the huge flock of Redwings roosting recently at Longridge Fell, 8 miles north of Preston. The latest estimations were of 25,000 Redwings flying to the plantations at dusk. 

I found Redwings, Fieldfares and Blackbirds galore along nearby lanes. The overnight frost which blanketed Northern England on Friday night had obviously sent thrushes far and near in search of food. Huge numbers scattered ahead of approaching cars along busy Moss Lane. 

Some of the Blackbirds were definitely “continental” types, immigrants from Northern Europe, distinguished by their mottled appearance, streaked throats, dark bills and general behaviour in sticking with their cousins the Fieldfares and the Redwings. I settled in one spot and waited for the birds to come to me.

Hedgerows provide food and shelter for many species. Because they often link small woods, they are essential corridors along which wildlife can travel. It is said that hedges may support up to 80 per cent of UK woodland birds, 50 per cent of mammals and 30 per cent of butterflies. 

Redwing

The ditches and banks associated with hedgerows provide habitat for frogs, toads, newts and reptiles. It is at this time of year that our protected-by-law hedgerows provide essential food for migrant and wintering species like Fieldfares, Redwings and Blackbirds.

That was an enjoyable morning.  In most years our Redwings and Fieldfares don't stay throughout the winter and have mostly departed for France and Iberia before the year is out.  It would be nice if they stayed just a little longer.
