Goldfinch News

Today we pay the price for the week or two of fine weather as cold northerly winds with snow hit Cumbria, Yorkshire and Derbyshire, north, south and east of this coastal location. This April surprise brought down the curtain on any springtime birds likely to head this far north and so put paid to any birding or ringing for me today. 

We received yet another Goldfinch recovery in the south of the UK. L863394, a fresh juvenile bird of the year caught on 2nd September 2011 during one of many ringing sessions at Rawcliffe Moss. It was recaptured at Cadborough, East Sussex just 44 days later on 16 October 2011. On 2nd September Will and I caught a total of 19 Goldfinches, a number which made up the majority of the catch of 31 new birds, so we probably hit an autumn movement of Goldfinches that day. 

During 2011 we ringed 280 Goldfinches at this site and this latest recovery is similar to ones notified in the past which show how Goldfinches from the north of England travel south in the autumn to spend the winter near the south coast and then return north in the spring. Yet others may hop across the English Channel to France, Belgium or Holland and we await a record of this type. I plotted the most recent example on the map below together with others involving the Fylde area of Lancashire. Three of those shown involve birds from Rawcliffe Moss, two individuals from mine and Will’s gardens respectively and the final one a road casualty. Interestingly five examples involve sub-adult females, the road casualty of unknown age. Juvenile and females Goldfinches are known to migrate further than males. 

In recent years the population of Goldfinches has increased tremendously in this part of Lancashire whereby they are now a very common garden bird plus a bird of farmland and woodland edge, all of which makes it possible to catch numbers only dreamt of ten years ago. So all you ringers there in the south of England, keep catching those winter Goldfinches, there’s a good chance one will be recaptured up here or you will find one originally ringed in the Fylde.

It’s No Joke

We met up at 0630 on the frosted moss again for another crack at dawn ringing. With it being April 1st I wasn’t sure if Will was pulling my leg when he said he’d caught and ringed a Snipe on Saturday night instead of staying in and watching the telly. 

The nets went up and then whilst having a warming coffee he showed me the pictures of the Snipe, one of several we’d seen on a tiny flash of water on Saturday when trying to locate the Ring Ouzel. Nice one Will, it is several years since the ringing group had a Snipe on the yearly totals.

We turned to the more immediate matters in hand; Sunday morning’s ringing which turned out to be quiet once again, unlike Portland Bill on the south coast of England where on Saturday thousands of migrant birds made landfall. Saturday - “all but impossible to get to a best guesstimate of the numbers but 3000 Willow Warbler/Chiffchaff, 500 Blackcaps, 75 Wheatears and 12 Redstarts seems reasonable at the Observatory where the day’s ringing total reached 615 birds!!” 

Unfortunately none of the thousands of that wave of migrants appeared to have travelled north overnight to the postage stamp of land that is Rawcliffe Moss, Lancashire, so we settled for the somewhat less impressive total of 11 birds, 9 new and 2 recaptures. We did get another 4 Lesser Redpoll together with 4 Goldfinch and 1 Reed Bunting. The 2 recaptures were 1 each of Goldfinch and Dunnock.

During the morning there was a small but evident arrival of Lesser Redpolls with probably 25/30 birds overhead during 4 hours. Little other noticeable migration except for a couple of Siskin, 10/12 Meadow Pipit and 2 flights of Golden Plover amounting to circa 50 birds. Other bird watching resulted in 1 Merlin, 1 Little Owl, 1 Kestrel, 2 Great-spotted Woodpecker, 4+ Skylark, 2 Jay, 3 Buzzard, 6 Yellowhammer, 4 Reed Bunting, 2 Mistle Thrush, 4 Grey Partridge.

Less Lessers

Will and I met up on the moss again today hoping the past week’s abundance of Lesser Redpolls might continue so we could attain the magic 100, but it wasn’t to be. The continuing northerly wind didn’t help our cause with just a small catch of new birds to reward 4+ hours in the field. 

We may have to wait for a change in wind direction before the next wave of redpolls, and at March 31st surely there will be more on the move during April? This morning we managed just 15 birds, 11 new and 4 recaptures. The new birds comprised 8 Goldfinch, 2 Chaffinch and a single Lesser Redpoll. Recaptures: 3 recent Goldfinch and 1 Chaffinch from 2010.

If it hadn’t been for the Niger feeders doing their stuff in attracting Goldfinches and ground feeding Chaffinches our catch would have been abysmal, with very little in the way of visible migration. In comparison to earlier in the week redpolls were conspicuous by their absence with less than 10 birds noted. Meadow Pipit movement was similarly negligible with 10+ birds heading north in 4 hours. 

“Otherwise” sightings: 6 Yellowhammer, 5 Linnet, 1 Corn Bunting, 4 Grey Partridge, 1 Fieldfare, 1 Kestrel, 2 Buzzard, 5 Snipe, 65 Golden Plover flying south, 1 Pied Wagtail, 1 Ring Ouzel briefly. Mammals: 1 Stoat, 20 + Brown Hares.

The BBC promised a change in wind direction overnight together with a less than 5mph wind, so the results tomorrow could be different again. And as we always remind ourselves “You don’t know until you try”.

The Lone Ringer And A Kite

No trusty companion for me today when the four letter word beginning “W” reared its ugly head for the other lads. Alone I went to Rawcliffe Moss hoping to find out more about the substantial Lesser Repoll passage which started last week and continues unabated. 

Another successful session saw a catch of 29 birds of just two species, 27 Lesser Redpoll and 2 Goldfinch, with once again nil recaptures. Today’s catch brings the total number of Lesser Redpoll ringed here to 81 individuals since 24th March, a tiny proportion of the several hundred which have passed over or through the site in the morning hours. 

A change today saw the redpolls arriving from a westerly, even north westerly direction, with a number of them leaving the site on the same axis by heading into the very slight south easterly breeze. In all I estimated 100+ redpolls this morning between 0700 and 1030 when I had to leave early for an appointment. Noticeable again today was the lack of males in the catch, just a single adult male from the 27, the remaining 26 either adult female or juvenile. Of these 81 Lesser Redpoll caught in less than a week, only 11 can definitely be allocated as males. 

The above makes me wonder if Lesser Redpolls adopt a similar wintering/migration strategy as other species and some finches in particular, i.e. young birds and especially young females migrate further south than adult males, and we are catching a number of birds leaving the south of England, France or Belgium and heading up to Scotland or Northern Ireland? None of the Lesser Redpoll caught this spring have carried noticeable fat deposits, and as diurnal migrants, even if travelling good distances, they are able to stop off and feed up quickly if required.

Processing birds alone kept me pretty busy and so limiting any bird watching, but of note were 6 Yellowhammer, 2 Buzzard, 1 Chiffchaff, 2 Grey Partridge, 4 Linnet, 1 Corn Bunting, 2 Reed Bunting.

 I was fairly well occupied with ringing so couldn’t find much time to take photographs today, and in any case they would only be more Lesser Redpolls wouldn’t they? The Roe Deer appeared in the half light of dawn when I switched to ISO3200.

Will tells me that after he got back home from ringing yesterday he watched a Red Kite over his house battling with both a Kestrel and a Buzzard.

More Redpoll, Chiff, And Lotti

More settled weather meant Will and I could try for more migrants on Rawcliffe Moss today. There was no mist this morning, even with the clear skies overnight. The 0630 start gave little sign of overnight migration in the quiet plantation with the only hint of newly arrived birds a single Chiffchaff on the first round of the nets at 0715. Once again most of the action began soon after dawn with birds overhead, the major players being a count of 65 +Lesser Redpoll heading north in four hours. Smaller numbers of Siskin today with, less than 12 and a stifled Meadow Pipit passage of 6 single birds noted.

Our catch today was 19 birds, another 17 Lesser Redpoll to add to the 30 of Sunday and 5 of Saturday. Other new birds today: 1 Chiffchaff and 1 Goldfinch. As we expect, there are no recaptures of Lesser Redpolls with all the birds moving rapidly from the site and continuing their journey north. An interesting aspect this morning was the lack of male birds, with just one definite and the remainder of the 17 redpolls first year birds or adult females. It is not always possible to be 100% certain of the sex of brown first year lessers unless they show the beginnings of red admixed with brown breast or rump feathering. Wing length gives a clue but there is overlap between males and females.

I'm still waiting to see if anyone claims Lesser Redpoll L977497, not one of our birds but one we caught on Sunday.

Birding was subdued again this morning with some familiar counts and observations: 1 Corn Bunting, 4 Yellowhammer, 1 Pied Wagtail, 1 Hen Harrier, 5 Buzzard, 2 Great-spotted Woodpecker, 60+ Curlew, 1 Pink-footed Goose, 5 Roe Deer. Still a single lingering Fieldfare in the same field as recent days.

When I got back home the Long-tailed Tits were busy lining the nest with feathers in preparation for egg laying. Both of the adults’ tails are beginning to show wear as they spend more time in the confines of the tiny nest.

Redpoll Rush

After yesterday’s trickle of finches Will and I met up on Rawcliffe Moss to see what today might bring. The morning began in similar fashion to Saturday with a cold, misty start which dictated very slow catching while the sun struggled to burn off the grey haze. We started at 0700, and just over two hours later at 0915 had amassed the grand total of three birds, all Lesser Redpolls.

As the mist slowly cleared birds began to move north as if waiting for brighter skies. Between 0930 and 1100 the dribble of redpolls turned into a veritable rush and we ended with 40 new birds, 31 of which were Lesser Redpolls, one of them ringed previously by someeone other than us - a "control"; Lesser Redpoll L977497 anyone?

So the 40 new birds comprised 31 Lesser Redpoll, 4 Goldfinch, 2 Chaffinch, 1 Yellowhammer, 1 Meadow Pipit and 1 Blackbird. The single recapture was a resident Blackbird.

Catching 31 Lesser Redpolls on a spring morning raises the question of how many individuals passed overhead during our 4 plus hours on site. Given the surge between of birds between 0930 and 1100 and the certainty that our catch was a proportion only of those heard and seen, often high above, we estimated between 100 and 200 individuals. It will be interesting to see today’s results from other observation points along the coast and inland. Overhead Siskins this morning numbered c20 with Meadow Pipits c30, low figures, but both of them high-flying species on a bright sunny morning.

Apart from the good number of Lesser Redpolls on the move our birding was unexceptional with a resident and singing Corn Bunting, 2 Buzzard, 1 Kestrel, 2 drumming Great-spotted Woodpecker, 2 Reed Bunting and 6 Yellowhammer. Two Little Owls this morning, one in each of their territories 400 yards apart.

STOP PRESS: 110+ Lesser Redpoll passed over Hilbre Island, Merseyside this morning, 40+ over Rossall near Fleetwood, with less than 20 over Heysham, North Lancashire.

Finches And Fieldfares

It’s been a slow start to the finch season with even Goldfinches hard to come by lately, but this morning’s ringing on the moss made amends with a sudden increase in the King Harrys and the start of the redpoll passage.

With recent quiet visits and the cold, misty start today I wasn’t too adventurous with the number or positioning of nets but caught fairly well until about 10am. New birds, 12 Goldfinch, 5 Lesser Redpoll, 2 Chaffinch and a single Coal Tit. The two recaptures were a Blackbird and a Goldfinch.

As the sun burned off the mist a few Siskins and more Lesser Redpolls flew north, however there was no sign of either Goldcrests or Chiffchaffs in the plantation, species we might expect by now. Otherwise the birding was subdued with 7 Yellowhammer, 45 Curlew, 2 Great-spotted Woodpecker, 3 Skylark, 1 Corn Bunting, 2 Buzzard and 1 Kestrel.

In the autumn it’s not always possible to sex Lesser Redpolls - no doubt about one of this morning’s males.

Fieldfares have used a nearby field for weeks now, all through the wet spell and even now as the soil dries out completely where the bird's brown tones merge in with the dry terrain. I stopped today to take some photographs of birds in a flock of about 130 as they intermittently picked over the earth than flew to the tops of nearby trees when passing vehicles spooked them. Take a good look, it may be November before we see them again. I saw a single distant Redwing amongst the flock but could have missed others.
