This And That

Tuesday 19 April - There was no traffic on the road when in the semi darkness a Barn Owl drifted across the road ahead. It’s a regular spot for Barn Owls and best visited when there’s a little more light. I pulled up, clicked a few shots and then motored on to my real destination.

When I arrived at the Pilling ringing site, all was quiet and the temperature gauge showed -1.5°C so I elected to employ just two nets, one at a time, so as to warm my hands in between. I reckoned that there would not be too many new birds around following the clear frosty night. 

I was right. Just 4 birds caught, 2 Blackcaps (male and female), 1 Reed Bunting and 1 Willow Warbler.

There was little else to see or to hear during the “one bird an hour” session. Although local reports mention other insectivores like Whitethroat, Lesser Whitethroat, Grasshopper Warbler , Redstart, Sedge Warbler, Whinchat and Swallows, the numbers are low, and those same species have yet to appear at our ringing site. 

Still, it wasn’t too bad sitting in the now warming sun, coffee and hot-cross bun at hand,  day dreaming of birds yet to come in May, home or away. 

Email news arrived of adult male Lesser Redpoll APN5870 caught at our ringing site Oakenclough, Nr Garstang on 14 April. It was another of the regular south to north movements that we have come to expect with our redpoll captures. 

In this case APN5870 was first ringed 62 days before in a suburban garden in Bracknell, Berkshire on 11 February 2022. This redpoll may have wintered in south-east England however I tend to think that it had more likely wintered across the English Channel and in February it was already migrating north to its eventual destination some way north of Oakenclough.

Perhaps the redpoll was looking to join with the huge numbers of Lesser Redpolls in the birch woods of Scotland. 

While not strictly “garden birds” Lesser Redpolls will visit bird feeders at certain times of year when their natural foods become scarce. The species seems to prefer niger seed (aka thistle or Nyjer), but the seed must be fresh and aromatic when they are more likely to find it and to return day after day. The species’ natural food is the seeds from birch, alder and spruce.

Like most finches, the redpoll family are susceptible to salmonellosis because of their flocking behaviour, therefore garden feeding enthusiasts must have a scrupulous bird feeder cleaning regime. 

On Thursday morning I checked out our Sand Martin colony to see how many had arrived and so as to guess when might be the first visit for ringing purposes. A stiff easterly wind blew dust and sand across the face of the colony as about 15-20 Sand Martins circled around.

None seemed interested in returning to old excavations but it was rather a cold morning for builders. I pencilled mid-June into the memory hole. 

Nearby were two pairs of Oystercatcher and a pair of Pied Wagtails, both of them probably a little further on with their year than the Sand Martins; especially since the Oystercatcher tried to see me off site in case I found his partner sat on eggs.

Back soon with more this and that. Don’t go away.

Insectpedia – A Review

I have been looking forward to meeting up with Insectpedia - A Brief Compendium of Insect Lore, the latest in the Princeton series of “Pedia” Books. My first acquaintance with this family of books came via Birdpedia in 2021 - Birdpedia .

And here is Insectpedia which is not on general release until early May but can be pre-ordered now from Princeton the publishers or other outlets. 

Insectpedia- Princeton Press
 
Princeton’s Pedia books are encyclopaedic but tiny in size; the series travel the wonders of the natural world, from A to Z. These brief compendiums cover wide ground in sympathetic, often funny, but always fascinating entries on the science, natural history, and culture of their subjects, e.g. Dinopedia, Geopedia, Treepedia, Birdpedia, Florapedia and Fungipedia. 

Every birder knows that birds and insects have a close relationship, in many cases interdependence based upon the fact that many birds eat insects; some eat them all year round, and migrate long distances to make sure of an abundant supply. Others eat them in the summer months and then switch to a more varied diet in winter when there are fewer insects around. Lots of bird species also feed insects to their chicks. 

Insects are an important part of the diet of hedgehogs, spiders, bats, fish, frogs and toads. Some insects eat other insects, including wasps, beetles like ladybirds, and ants. Another crucial role that insects play is in pollination, helping plants turn their flowers into fruits. They also contribute to the breakdown of plants and animals after they die, helping to keep our environment clean. 

Insects have been a part of the human diet for many thousands of years, and many cultures still relish insects as food. Increasingly the cultivation of nutrient- efficient insects may be seen as a way of feeding the booming human population. There’s food for thought! 

Insectpedia- Princeton Press

Insectpedia has an explanatory Preface with hints as to what a reader should expect, but unfortunately there is no list of Contents, nor at the back of the book, an Index. This is only slightly irritating, whereby as well as a cost-saver it could be a deliberate ploy to make the reader visit and enjoy every page in one or two sessions, something that I was happy to do. 

Each subject matter has but one or two pages in which to grab the readers’ attention and Eric R. Eaton’s engaging, enthusiastic style invariably tempts the reader into his lair and looking for more. 

 
Insectpedia- Princeton Press
 
Insectpedia- Princeton Press
 
There are dozens of entries in the 200 pages and many “chapters” of these miscellaneous chunks of reading set in in alpha order with topics ranging from ‘A’ for Acarinaria, bees or wasps that carry squadrons of cleaning mites, right through to ‘Z’ and Zombie Lady Beetles. In between there are Camel Crickets, Exploding Ants, Jumping Beans, The Schmidt Sting Pain Index, and Flea Circus, the latter a remarkable and unlikely entertainment that thrived as late as the 1980s. Yes, millenniums, I remember as a pre-Internet child being taken to see one such circus where I emerged into daylight enthralled if a little itchy. 

Insectpedia- Princeton Press
 
Vespa mandarinaria aka “Murder Hornet” tells a cautionary tale of how global media, irresponsible journalism and click-baitery can induce widespread irrational fear. Now where else have I read that recently? 

Eric R tells the tale of the Weta, or Wetapunga, the Maori name for the Giant Weta, a nationally endangered species of New Zealand but now confined to a few remote islands. This three inches long beast lays claim to being the world’s heaviest insect by weighing in at over 70 grams, the weight of our UK Song Thrush. 

Who knew that we Homo sapiens share 60% of DNA with Drosophila melanogaster and that 75% of the genes known to cause human disease can be found in fruit flies? Insectpedia is crammed with such curious facts and figures about the creatures we love to hate or to fear in equal measure. 

And while Hilltopping may soon become the latest trend in sexual penchants at your local park, it is a way that some butterflies, wasps, ants, beetles and dragonflies use promontories as rendezvous sites for mates. Hilltopping is a form of lek polygyny, or lekking, a term familiar to all birders. 

This review with the examples above gives just a taster of the insect goodies found in this fabulous little book. It is highly readable, informative, engaging, occasionally witty, and mostly light-hearted in a way that should actively encourage a spirit of inquiry and further investigation from any reader. 

Mention must be made of Amy Jean Porter’s black & white illustrations dotted throughout the 200 pages and which accompany many entries. These are mostly delightful or instructive, and occasionally chilling when combined with a specific subject, as in the Tsetse Fly portrait at Page 169. 

Insectpedia is quite simply a terrific little book and amazing value for money in this rip-off age of consumerism. Eric R Eaton and Princeton must be congratulated for this latest winner in the series. 

Please birders or otherwise, buy this book. At £10 it’s a fraction of the stinging cost of a tank of petrol.

Slow Burn

The spring has been Slow Burn rather than Fast Track North. A couple of weeks of cold weather put a damper on northerly migration and at some point these birds have to get a rush on to bag the optimum breeding spots. 

Local bird and WhatsApp news tell of ones and twos only of Willow Warblers, Chiffchaffs and Blackcaps, all species that normally arrive in a rush in early April. Hardly anyone has reported Swallows or Sand Martins or even Wheatears. House Martins are a distant dream and Swifts a Lottery Prize. 

Thursday morning and at last warms winds from Atlantic West Africa might well deposit both variation and numbers in the hills above Garstang where Oakenclough became the destination and a meet up with Andy and Bryan at unearthly 0615. 

Birds caught: 8 Willow Warbler, 3 Lesser Redpoll, 2 Chaffinch 1 Goldfinch, 3 Coal Tit, 1 Chiffchaff, 1 Blackcap, 1 Blackbird. 

At last then, a few Willow Warblers caught, some from previous seasons and as we might expect for mid-April, mostly males and one female. Female LDL516 had been first ringed at Oakenclough 4 June 2020, male LDL808 first ringed on 11 May 2021.

One of the Lesser Redpolls came with a ring from elsewhere. APN5870 was not one of our rings and may have been ringed north or south of our recapture. After the holiday break we will find out where it was originally ringed. 

Visible migration was nil except for two Swallows while a total of 20 birds caught is better than recent efforts as we await the arrival of species such as Garden Warbler, Whitethroat, Lesser Whitethroat and the two flycatchers, Pied and Spotted. 

The holiday weekend will be family time with probably no birding or ringing until Tuesday next. Log in then to Another Bird Blog for the latest news on Spring 2022. 

Next week will also see a book review here on the blog, a new book that will interest many birders and wildlife enthusiasts. And it’s a ten quid bargain!

An Improving Picture

The temperature readout showed -1°C and warned of “possible icy roads”. It was 0530 as the wipers scraped across the icy windscreen. I pressed the heated seat buttons, one for me and one for the jacket draped over the seat. I was driving to meet up with Andy and into the hills of Oakenclough where it’s always two or three degrees colder than the Fylde coast. 

Over Rawcliffe Moss the car lit up two Roe Deer frozen in the approaching main beam so I slowed and turned off the lights so as to let them walk across the fields towards the rising sun. It’s best not to panic wild deer into a mad dash, especially if there are fences nearby. 
 
Roe Deer

As ever, and after a couple of poor catches out Pilling way we hoped that things could only get better, despite talk of continued cold weather in Spain, Portugal, and France, countries through which our migrant birds must pass before reaching the UK. 

We caught migrant and newly arrived Chiffchaff and Willow Warbler in the first hour but then faltered through until 1030 without catching anything too exciting in the way of species or numbers. 

Goldfinch, Lesser Redpoll and Coal Tit were caught at feeding points while Coal Tits are something of a local speciality because of the proximity of a stretch of conifers. 

15 birds of 9 species caught - 3 Great Tit, 2 Lesser Redpoll, 2 Goldfinch, 2 Robin, 2 Coal Tit, 1 Wren, 1 Dunnock, 1 Willow Warbler, 1 Chiffchaff.

Redpoll News

After the promising warmth of late March the first week of April saw a plunge in temperatures, cold northerly winds and the return of rain. The week has been pretty miserable with no opportunity for ringing and little in the way of birding news here on the blog. 

In absence of anything more, I’m posting news of a couple of recently notified Lesser Redpoll recoveries from birds previously ringed at our site at Oakenclough, Near Garstang. The second one reinforces the cold weather effects of early April.   

Lesser Redpoll ALJ4397 was first caught on 12 August 2020 when it could reliably be aged as a bird born in that same summer. In August 2020 it was just a few months old, without any obvious male or female plumage characteristics, so was databased as a “juvenile/first summer”. 

Lesser Redpoll

Lesser Redpoll - Oakenclough to Woolston Eyes

The same individual was recaptured by Merseyside Ringing Group on 13 March 2022 at Woolston Eyes, Warrington, 577 days after the first capture. By now and after a period of 577 days of plumage changes the Merseysiders were able to see that ALJ4397 has become an adult female. 

Woolston Eyes, Merseyside

It seems likely that on both occasions ALJ4397 was caught in the act of migrating, on 12 August 2020, heading south and on 13 March 2022 heading north, both dates suggestive of a Scottish origin. 

+++++++++++++++++++++++++++++++++ 

The second redpoll, one from this very same week of cold weather, Lesser Redpoll AKE3862, another first year individual of indeterminate sex was captured at Oakenclough on 13 November 2019. 

Lesser Redpoll

This redpoll was found dead on 3 April 2022 at Langholm, Dumfries and Galloway, Scotland during a spell of very cold weather. 

On the information report, the finder remarked that AKE3862 was “Freshly dead - within about a week. Poor condition indicating cold weather. Temperature at night around freezing for the past four nights”.  

872 days had passed since the original capture with nothing in between to indicate where AKE3682 had been in those interim seasons or during migration times. 

Lesser Redpoll - Oakenclough to Langholm, Dumfries and Galloway

Langholm, Dumfries and Galloway, Scotland

As in the first example above, but now in a more obvious way, it seems that AKE3682 was a bird of Scottish origin heading south on 13 November 2019 and then on 3 April either arriving at its migration destination in Scotland or about to continue to a more northerly journey's end.

The weather is looking more promising for Saturday now. Fingers crossed for more news, views  and pictures to entertain regular blog followers.

Staying Grounded

Saturday 26 March. There was a cold start at 0600. The temperature gauge displayed 2°C as I erected nets alone while musing over what the next four or five hours might bring. 

During the week bird news from Merseyside, North Morecambe Bay and North Wales confirmed my observations of the early week - low-key migration with small arrivals of Chiffchaffs, Lesser Redpolls, Goldcrests and Wheatears, together with unusually low numbers of Meadow Pipits in the run of clear-cold mornings. 

In North Wales there was an early Willow Warbler on Thursday 24 March together with nine Black Redstarts! I was expecting most of the above but definitely not a Black Redstart, although it was almost 12 months ago to the day of April 1st 2021 that I unexpectedly saw a Common Redstart perched at the gateposts. 

Common Redstart

By 0630 I was up and running with a cup of steaming coffee, the car ticking over and the heater turned to “Hi”. 

This site at Pilling is certainly good for Reed Buntings, already the most ringed bird here for 2022 with another three on the books today.

In the furthest mist net lay yet another Brambling, one that at first glance looked identical to the Brambling caught on Thursday. When I turned the bird over to begin extracting there was no ring on either leg and I could see that this was also a second year female, marginally paler than the one of Thursday. 

Unlike us in the grey winter of Northern England the Bramblings may have faded in their winter sun destinations of France, Iberia or The Cornish Riviera. 

Brambling

Brambling

From here on the west coast Bramblings have a long journey yet before they reach their eventual destinations of Scandinavia and further east, into that presently troubled part of Northern Europe. Bramblings breed in coniferous and birch woodlands in much of Scandinavia, a large part of Russia, and northern Kazakhstan and Mongolia. 

Brambling Range in Europe
 
I gradually shed layers of clothes as the sun rose higher and grew increasingly warm. Unfortunately the clear blue skies and zero wind probably helped birds to move off site very quickly. A couple of Lesser Redpolls, 2 Pied Wagtails, Blackbirds and a singing Chiffchaff all evaded the nets and I was left to birdwatch rather than ring birds. 

Chiffchaff
 
There were lots of “pinkies”, Pink-footed Geese, around this morning, with perhaps an influx of those that wintered in Norfolk and South Lancashire, birds now ready to set off for Iceland. There seemed to be many hundreds, even thousands, over 3,000 of them when they panicked from their feeding in the Cockerham meadows when the regular aircraft climbed off from Black Knights Parachute Centre loaded with thrill seekers. 

Pink-footed Geese
 
For adrenalin junkies there’s the opportunity to throw your body out of a light aeroplane for as little as £199 with a “One Jump Taster”.  With luck you will land in Cockerham and not in Morecambe Bay.

Black Knights Parachute Centre - Cockerham Marsh
  
I think I will give that a miss, stick to solid ground and watch from below rather than have the ground rush up to meet me. 

Other birds seen today – 3 Little Egret, 2 Skylark, 1 Buzzard, 8 Linnet, 1 Lesser Redpoll, 2 Meadow Pipit. 

Andy is back from Egypt this weekend, keen to show off his sun tan and eager to get out ringing again, if slightly miffed to miss two Bramblings. Let’s hope bird numbers improve soon for his ringing fix.

Quality Not Quantity

There goes that old chorus again, the one that ringers use when numbers are low but there are a few goodies to shout about. 

Until today the week was a little breezy for the Pilling site where even a breath of wind blowing through the bare hawthorns wafted a mist net around and made it visible. This morning was slightly better with zero wind and by now, after a couple of sunny days, green leaves and blossom in place of bare branches. 

Although by the end of March there are migrant birds to see the main bulk of migration of insect eating passerines is still three, four and more weeks away. I hoped to catch a few Meadow Pipits, a species that migrates north in good numbers in March but there seemed to be few around and I thought maybe they were high up in the cloudless sky with no reason to landfall. 

In fact visible migration was rather poor with small numbers of Lesser Redpolls and Reed Buntings being the most numerous. Just 9 birds caught – 5 Reed Bunting, 1 Goldcrest, 1 Blue Tit, 1 Lesser Redpoll and 1 Brambling. 

The Brambling, the second one caught here this spring, was a subtle looking second year female without the black and bright orange shades of the male caught here a few weeks ago. 
 
Brambling
 
The redpoll likewise proved to be a second year female. A second Lesser Redpoll escaped the net before I could reach it when I was forced to deal with a Mallard crashing about in another mist net. The nets are not designed to cope with wayward Mallards. Fortunately the duck found a way out without damaging the fairly new £90 net. 

Lesser Redpoll

Goldcrest
 
Other birds seen and heard - 20 Linnet, 6 Lesser Redpoll, 3 Blackbird, 1 Kestrel and 1 Snipe. Wintering birds comprised over 300 Pink-footed Geese on nearby meadows where their stay will soon be ended by a flight to breeding grounds in Iceland. 

Kestrel
 
I disturbed the Snipe when crossing a still soggy field on my way to the seed plot and where over the winter we had caught Linnets. An escaping Snipe or two became a regular feature of most days when splashing across to the seed plot. The Linnets are no longer with us in any numbers with so many gone north, hopefully to the top of Scotland where with luck one or two will be recaptured by Scottish colleagues. 

Snipe

Back soon. Maybe even Saturday if these winds stay down and high pressure stays around.
