Trapping at Pilmoor

Another 2.5 hours with a lamp at Pilmoor, although it felt chillier than the minimum of +6 recorded.   Fewer moths than Saturday night, but still a respectable haul:  a Tortricodes alternella, 30 Yellow Horned, a March Moth, four Oak Beauty, two Engrailed, 38 Small Quaker, two Common Quaker,  23 Clouded Drab,  eight Twin-spotted Quaker,  three each of Hebrew Character and Chestnut.

Yet more gulls

Since the last entry, visits to Allerton Park tip as it is referred to in the Yorkshire Bird Report, have continued daily.  On Friday 9th, a 1st-winter and 2nd-winter Iceland Gull, two pale-winged argentatus (one of which was new with slightly darker tertials and primaries and paler head), and the 2nd-winter Glaucous Gull with the missing primary.
A late visit on Saturday 10th produced very few gulls, and only a 2nd-winter Iceland and one pale winged argentatus were seen.  However, earlier in the day, Paul Irving had seen the Kumlein's Gull there, along with several Iceland Gulls and the 2nd-year Glaucous with the missing primary, and up to seven Red Kites.

A morning visit this morning, again not more than 200 gulls in total.  However, gulls floated in and other left, so at times there were no white-winged gulls, and at one time there were two 2nd-year Iceland Gulls, and two 2nd-year Glaucous Gulls present.  One of the Glaucous Gulls was a new bird, with a complete set of wing feathers, and a greyish cast to the pink bill.

There have been small numbers of obvious adult argentatus among the argenteus,  and here is a photo of an adult of each next to each other, showing the characteristics well.  When similarly aged gulls are not so close together for comparison it is much more difficult to discern.

As a round-up for the total number of odd gulls at Allerton Park Tip, I would say as a minimum there have been three Glaucous Gulls, ten Iceland Gulls, a Kumlein's Gull, three pale-winged argentatus, a Caspian Gull and  three Kittiwakes.  Not bad, eh?

Trapping at Sessay Wood, Pilmoor

I spent 3 hours trapping with a light over a sheet at Sessay Wood last night, and there were plenty of moths about, with by biggest ever March catch.  This in addition to an interesting night sky, with Mars, Jupiter and Venus all showing well, and missed Mercury in low cloud at sunset.

Species
13 Tortricodes alternella,  two Acleris ferrugana/notana,  143 Yellow Horned,  eight March Moth, seven Brindled Pug,  16 Oak Beauty,  four Engrailed,  147 Small Quaker,  six Common Quaker,  19 Clouded Drab,  nine Twin-spotted Quaker,  11 Hebrew Character,  two Early Grey and four Chestnut.
4 Chestnut.

Charlie advises me this is a record count of Yellow Horned.

Still an interesting bird...

Even better views of a pale-primaried gull and distant views of another one that was sleeping, at Allerton Tip.  Today's bird, if it was the same as yesterday seemed to be the same size and build as Herring, and was seen well including in flight.  I presume the bird at Farnham was one of these birds, and I am now happy that it (they?) are probably argentatus from the pale extreme.  An interesting bird nevertheless.

In addition, there were a 1st-winter and a 2nd-winter Iceland Gull, a Red Kite and up to four Buzzards.  To finish off, one of the singing Hedge Accenters,  presented itself next to the car, and at least I can identify them.....

Hold fire on the Kumlein's Gull......

At Allerton today, I visited early afternoon, and with the wind direction, sunlight and where the gulls were, good views were had of many of the gulls, although some were still fairly distant.  The highlights today were two 1st-year Iceland Gulls, two advanced 2nd-year birds with olive/orangey yellow bills with no dark tips, also the 2nd-year Glaucous from yesterday.

I came across this 1st-winter bird with washed-out tertials and primaries, probably the same as that seen at Farnham, and had several minutes view at 150m range, although it was asleep for the most part.  It briefly raised its head to reveal a small head, neat all dark bill with a hint of pale (red?) at base.  Of c1000 Herring Gulls present, it was the only one showing any hint of such washed out primary-tips.

The options are that it is (a) an Argentatus Herring Gull from the pale end of variation, (b) a Kumlein's Gull from the darkest end of the spectrum, (c) a hybrid (although presumably not x Glaucous due small size and small dark bill), or (d) a leucistic bird.  I am open to suggestions, and any thoughts or comments would be welcomed.

Another great morning

With the forecast for Wednesday looking so poor, and the sun shining brightly again this morning despite the early frost, I just had to go and take advantage of the bright sunlight at Allerton.  Not many gulls on arrival and certainly nothing of note, and many of them drifted off towards the tip.  Still it was pleasant sitting in the car listening to singing Hedge Accentors, Reed Buntings and Tree Sparrows calling, and Long-tailed Tits working their way up and down the hedgerow.

Some loud shots at the tip, presumably bird-scarers, brought most of the gulls on to the wash-pit, including two Iceland Gulls, an obvious 1st-winter, and a 2nd-year.

Iceland Gull, 2nd -year

No raptors for the first two hours, but then two Red Kites and up to six Buzzards circling on thermals at some height above the site, their presence only given away by their constant calling.

Allerton tip

What a fantastic morning, bright blue sky and sunshine although the stiff breeze was a bit on the chilly side.  I spent several hours at the washing pit next to Allerton tip, and although all the gulls were facing the same way into the wind, unfortunately they were mostly tail on.  Still, had some good views of the assorted gulls present, and at least 3 Iceland Gulls, probably all 2nd-years, and a 2nd-year Glaucous flew over, perching briefly on the far shore.

2nd-year Glaucous Gull

After a couple of minutes it took off with most of the other gulls and one of the photos I took managed to get it and an Iceland together.  Interestingly, there is a hint of a tail-band showing on the Glaucous, so possible some Herring Gull genes in there somewhere, and it also has a primary missing and some oil on the left wing.

Every now and again, the gulls would fly up, often due to one of a couple of Red Kites which flew back and forth over the site.

A small selection of other gull photos were taken.  The vast majority of birds present were immature birds, as one would expect for species that take 2-4 years to become full adults.
