Fifty Up

It’s ages since a ringing session hit the fifty birds processed mark.  When I met up with Will and Andy at the Sand Martin colony at 0700 this morning it didn’t seem likely that this day would be any different. Tuesday had seen downpours with inches of constant rain between midday and midnight but where weather forecasts still confirmed that Wednesday would be a “goer”. 

Early cool and 100% cloud cover saw very few Sand Martins around; we really thought we might struggle into double figures given the lack of activity at the nest holes. As the morning warmed and the sun appeared, things began to look up with Sand Martins on the move, joining in with the activity around the nest holes and over the feeding area of the fishing lake. 

By 1110 hours when we tallied up and packed in we had caught 50 new Sand Martins from an estimated count of 150-180 individuals. That would mean a catch of at least 33% of those birds seen, an unlikely ratio and therefore more likely that the number of martins around was actually above 200.

Field Sheet. First Page.

The field sheet showed 12 new adults, an equal split of 6 males and 6 females, plus 38 juveniles. Interestingly, we had zero recaptures from earlier in 2023 or from previous years, another indication of post breeding dispersal from other sites.

Other activity saw a juvenile Kestrel trying its luck around the martin nest holes, an unsuccessful ploy that also failed for the adult Kestrel we caught here on 14 June. 

 

When we arrived just before seven Will spotted a small flock of 15/20 Black-tailed Godwits flying some distance away, perhaps looking for rain soaked fields in which to feed. About mid morning we realised that two of the godwits had landed a field away from our processing point. The two appeared to be of the Icelandic islandica race by way of their very strong brick-red colouration.

April produces the largest flocks of Black-tailed Godwits which correlates well with the bulk of breeders arriving in Iceland between mid April-mid May. The second half of May and early June is considered late for islandica to be in England and it is presumed that these birds are non breeders that may spend the summer here. 

Other birds seen - 4 Common Tern, 1 Common Sandpiper, 6 Tree Sparrow, 2 Pied Wagtail. 

A good morning was had by all.  Come back soon for more news, views and photographs.

Testing Times

The thunderstorm of Saturday moved north and east from here in coastal Lancashire and headed across the Pennines to disrupt the Headingley Test Match. There was less cricket to watch on TV but the Sunday forecast was unimpaired; a dry, bright morning with 2-5 mph and the prospect of a ringing session following weeks of inactivity. 

The rain was gone when I met up with Will for a brutal 0600 start but high hopes of catching a few warblers. Viewing visits in recent days saw seven or eight singing Reed Warblers and pairs of both Reed Bunting and Sedge Warbler with plenty of feeding activity around their reed bed of choice. Surely by now, early July there would be fresh juveniles aplenty? 

Our own scoreboard saw an improvement with 16 birds caught – 2 recaptures (Wren and a Reed Warbler from 2021) and 14 new birds. 6 Reed Warbler, 2 Blackbird, 3 Great Tit, 1 Blue Tit, 1 Robin and 1 Whitethroat. 

Score sheet

 

Of the seven Reed Warblers just two were juveniles, the other five adults, numbers that meant we had scratched the surface, with more juveniles yet to fledge following the very slow start to breeding during the cold weeks of May. Reed Warblers need dense and tall reeds in which to hide their nests suspended between solid reed stems, growth that was sluggish and not to anyone’s liking.

A single Whitethroat was the other representative of the warbler family with no sight or sound of hoped for Blackcaps, Willow Warblers or Chiffchaffs, never mind more exotica like Lesser Whitethroats or Garden Warblers. The singing Reed Bunting stayed out of range and we never got to see the female buried somewhere in the edge of the reeds on her precious eggs,

It looks as though we will have to wait a week or two more for post juvenile wanderings to begin in earnest. 

Bird watching in between the ringing provided scant rewards with handfuls only of Goldfinches, Linnets and Swallows plus flybys of Grey Heron and Little Egret. 

Later,  I caught up with the cricket. England beat the Aussies in the Third Test. Now it’s all to play for in the following two games, Old Trafford next and then The Oval for the decider. 

It’s a little like ringing. Playing to win and not giving up. You can’t keep a good team down. 

 

Avocets

Yours truly together with Andy and Will visited the Sand Martin colony on Wednesday where we caught 25 martins. Here’s a LINK  to that day for readers to catch up. 

During our 4 hours of work with the Sand Martins we noted a pair of Avocets across the more distant, quieter area of the farm that has less traffic from farm vehicles. The larger farm contains fishing lakes where anglers often occupy the wet edges of two other pools that would otherwise be attractive to Avocets and the like. The Avocets were very vocal across a wide area and engaged in aggressive bouts of chasing off passing crows and gulls. as well as surveying us from above.

It seemed fairly obvious that the adult birds had youngsters in tow and were in the process of showing their chicks the ropes while letting them explore their immediate birth area. It’s a process that birds must go through so as to prepare youngsters for when they go it alone. 

 

Avocet

 

We three met up again this morning in the hope of locating and then ringing the chicks, Andy with his trusty landing net, me and Will with binos and sharp eyesight respectively.  Three heads and three sets of eyes are better than one when finding wader chicks that can run, hide, swim or submerge, often all three. 

And so it proved. As soon as we approached the pool we thought might be the one we saw three chicks almost together at the edge of the pool, chicks of the perfect size for ringing. Within a couple of minutes all three Avocet chicks were in the landing net, then quickly ringed and released to their parents close by.

Note: Avocet Recurvirostra avosettta is a specially protected species. 

All birds are protected in some form, but some species have additional protection during the breeding season as do their nests, eggs and dependent young. To disturb Avocets and other species we have a special licence in advance. 

In England and Scotland, permits for ringing and/or nest recording are issued by the BTO on behalf of the relevant Country Agency; licences for other activities are issued directly from Natural England or NatureScot. In Wales, all licences are issued directly by Natural Resources Wales but ones for ringing and/or nest recording are applied for via the BTO, British Trust for Ornithology.

Log in soon folks. You never know what might be in the news with Another Bird Blog.

 

After The Thunder

Monday evening saw thunder and lightning rolling around the area followed by late night downpours. But we stuck to the pencilled in plan and hoped everything would be on song for Tuesday 0630, a visit to the Sand Martin colony at Cockerham. 

Tuesday morning began fine, the rain and thunder long gone to leave a cool, almost idyllic morning at the colony. The 0630 start had left the birds a couple of hours or more feeding time before we intruded upon their space. 

Two previous visits of 17 April and 26 May saw a total of 32 captures, 17 females, 14 males and one indeterminate sex of the April visit. This almost mid-June visit would almost certainly result in a catch containing a percentage of youngsters and thus, together with noting brood patch progress, assessing the breeding success of the colony so far. 

The colony is concentrated in one small area of the quarry face and estimated to be 60/70 active holes, not huge by Sand Martin standards but the only Sand Martin colony for a good number of miles around and therefore a valuable and unique addition to local flora and fauna. 

Sand Martin colony

 

We caught 25 on this latest visit, 12 adults (9 male, 3 female), three of them recaptures from earlier in the year; and 13 juveniles of the year. 

Adult Sand Martin

Juvenile (3J) Sand Martin

 

We sex Sand Martins and many other species by examination of their cloacal protuberance in the case of males, and for females by her brood patch (bare belly) progress. Males of some species develop a partial brood patch that is not as extensive as that of a female, a bare region of the undersides that at the peak of incubation lacks any feathering at all. 

Almost all birds incubate their eggs: keeping them warm while the embryo develops into a chick. In order to transfer heat better from their body to the eggs, many birds develop brood patches (a.k.a. incubation patches). The bird loses feathers from the belly, and the bare skin becomes wrinkly and swollen with fluid. Brood patches are a good way to tell what breeding stage a bird is at, since usually the brood patch begins to develop during nest building, becomes very swollen with fluid during incubation, and then declines. 

Brood patch

 

Juvenile Sand Martins that spend a couple of weeks in their nest tunnels often emerge carrying swollen and unsightly blood sucking hippoboscid ticks that have attached their body parts through feathers and into the birds’ skin. The one pictured below had six such ticks on its head.

Sand Martin

We can remove the insect with a careful grasp of the blood-filled tick using ringers' pliers and then a slow and gentle twist & pull action that releases the parasite. 

A bonus came with the catch of a feisty second summer male Kestrel when it tried to snaffle a Sand Martin but didn't count upon a mist net across it's normal approach line. There was some evidence of predation of the colony by the amount and type of feathers on the ground immediately below the nest holes.

All in all a very successful morning. Back soon with more news and views from Another Bird Blog.

Fifty Up

All week we had Friday pencilled in for a trip to Oakenclough where the hillside location a mile or two above Garstang requires a still and preferably sunny day. The Autumn/Winter weather of 2022/23 had kept us away for months. 

Fortunately for us and any birds still around the area, Will had kept the feeding regime going with good numbers of finches in attendance. He confidently predicted a catch of 20 plus birds. 

We met up at 0730 to a cold but fairly bright start. The morning improved, cloud broke and the sun arrived following a spot of drizzle and a rainbow to the north that lit up distant Morecambe Bay.

Will’s prediction was off the mark when we finished at 1130 with 54 birds in the bag. Goldfinches formed the majority of the catch - 37 Goldfinch, 9 Chaffinch, 4 Blue Tit, 3 Coal Tit and a single Lesser Redpoll.

It wasn’t too obvious that so many Goldfinch were around, they just arrived in fours and fives all morning. We counted about 15/20 Siskins flying over while the Lesser Redpoll seemed to be the only one of their kind. 

Otherwise a quiet morning with a single Grey Wagtail at the water’s edge and a distant Raven.

At Last

At last, a cause for celebration via a ringing session at Pilling planned for Friday morning. The one prior to recent foul weather was more than 6 weeks ago, back in early December 7 of 2022. That six weeks of zero ringing is something of an unwanted record breaker. 

Whilst the lack of ringing meant we caught no birds it was essential to continue the supplementary feeding regime set up in November, a system designed to help wild birds negotiate the winter. However the weeks of wet, windy and occasionally cold weather also caused birds to leave and seemingly not return. 

During December hungry sheep had stripped the seed plot of remaining growth whereby the few Linnets that remained had departed wholesale along with the few Reed Buntings, Chaffinches and Meadow Pipits that began to use our open buffet. 

Last week we took the opportunity of a frosty morning of minus 4° to conduct maintenance work – cutting stray branches, widening net rides and constructing skulk piles in readiness for the coming spring. A few hours on site gave optimism with sightings of Reed Bunting, Chaffinch, Blackbird and even thirty or so Fieldfares that stopped by briefly to chuckle at our endeavours. 

 

Fieldfare

Blackbird

On Friday I met up with Andy and Will for the 0745 start and a slight improvement in the temperature to -1°. 

As expected the ringing was quite slow, the birding interesting, but not thrilling apart from a lightning fast Merlin. We caught just 13 birds – 4 Robin, 3 Reed Bunting, 3 Chaffinch, 2 Blackbird and 1 Blue Tit. 

Three of the Robins were seen to be recaptures, individuals that have survived the winter so far and probably now in the business of sorting out territories for the coming weeks.

All three Reed Buntings were new to us birds in what is prime wintering habitat of farmland with reed and woodland edge.

Chaffinch

A female Merlin appeared as if by magic when a handful of Meadow Pipits lingered around the remnants of the game cover crop, the pipits split up and scattered by the speed of the Merlin’s approach and their own panic attack. The Merlin singled out a pipit to chase but didn’t catch, flew off out of sight and then came back, as if to see if the pipits were still around. When the pipits were not to be seen the Merlin flew off into the distance before settling in a bare branched tree some 200 yards away. The raptor stayed in the tree for twenty minutes and more before departing at some speed.

Other birding gave us a single Grey Heron, 2 Little Egret, 1 Mistle Thrush, 13 Linnet, 8 Reed Bunting, 12 Meadow Pipit, 65 Whooper Swan.

Sticky Times

The forecasts for Wednesday proved to be on the wrong side of marginal. Luckily I’d already decided to drive and top up the feeding station without taking the ringing gear. The Fiat splashed through deep puddles of the days and weeks before as I looked for a less sticky spot to park up and disembark. 

I’d made a good decision as the wind was a tad strong for any netting and this would be a day for dropping a bucketful of supplementary seed and a quick look around. 

A Cetti’s Warbler greeted me with a burst of rapid-fire song as if it was trying to attract attention but I didn’t even look from where the song came because I knew the chances of seeing the bird were close to zero. And anyway, a few seconds later it would be gone and singing fifty yards away. 

Fifteen and more visits to Spain’s Balearic Islands where the Cetti’s is both common and widespread taught me not to waste time in trying to actually see a Cetti’s but to instead enjoy its song and eccentric behaviour. While morning and evening can be best, the colour, size and the habitat a Cetti’s chooses makes for challenging birding. 

Cetti's Warbler

 

It’s no different here in the UK where hardly anyone sees the skulking, evasive Cetti’s Warbler, a little bird with one of the UK’s loudest and most distinctive songs. It’s thought that by hiding away and singing loudly and forcefully from different parts of its territory, a Cetti's can fool rivals into thinking there are several males present, making the interlopers less likely to stick around. This behaviour allows a male to then have two or three females in his territory and thereby increase the success of his own lineage. 

Chaffinches, Reed Buntings, Long-tailed Tits and Greenfinches criss-crossed the net ride in search of the scattered seed. I watched for a while and then dropped seed on the whoosh netting square where the cleared and flattened ground held puddles formed by the days and weeks of rain.  A couple of days of wind and sun would dry the square - if only.

Chaffinch

It was Saturday before the wind and rain presented a real window of opportunity by way of a 5mph wind or less across a number of forecasts. It was time to have another go. I met up with Andy and Will at 0700 where the partly flooded farm track glinted in our combined headlights. There was mist which hung around until the sun burnt it off around 10am.

With a little drainage work we made the whoosh net area usable if a little muddy, dropped more seed, set the single panel net to one side of the flooded walkway and erected three nets in the woodland edge.

The morning began, the mist refused to clear, but eventually it did and the catch improved a little. We finished at 1130 with a nice and varied catch of 25 birds -  7 Chaffinch, 5 Linnet, 4 Meadow Pipit, 3 Redwing, 2 Reed Bunting, 1 Greenfinch, 1 Wren, 1 Robin, 1 Blackbird.

Today was one of the better Chaffinch days, yet another farmland species that is seeing a serious decline in its population. One of the males today, with a wing length of 95mm, was possibly of Northern European origin, a type we are seeing less of in recent years. Our UK Chaffinches are generally smaller, both males and females.

A good morning was had by all and we'll be back another day on Another Bird Blog.
