Grebes & Divers

Some shots of the Black-necked and 2 Slavonian Grebes that are currently in Ballynakill Harbour at the moment. The Black-necked Grebe was a long overdue county tick for myself. Up to ten pairs formerly bred at Levally Lough near Tuam from 1949 - 1956. Since then there have only been a handful of records. Up to 250 pairs bred at Lough Funshinagh, Co. Roscommon at one stage but these are all since long gone. I managed to get some record shots of the grebes as we were passing by them yesterday on the RHIB on the way out to Inishshark for the annual Grey Seal pup census (a little late this year). The Great northern Diver was photographed the previous day off Tully.

Pink-footed Goose Second Part

A few more of the Pink-footed Goose that's currently residing at Rusheenduff Lough.

Pink-footed Goose

A few pictures of a very tame juvenile/first-winter Pink-footed Goose on Rusheenduff Lough beside Renvyle House Hotel on Wednesday. It had been associating with a few feral white farmyard geese for a week now and has been fed Oats by the staff of the hotel with the other geese each morning. I 'd believe it could well be a wild bird but may have got separated from its family group and/or may be injured. It's not at all unusual for the odd wild goose to tag up with captive/feral geese. Nice to see it at such close quarters.

Adult Kumlien's Gull, Ross Beach

I found this adult Kumlien's Gull today down at Ross Beach. It was busy preening away with its head stuck in its mantle initially. The large size combined with the amount of black on the primaries lead to thoughts a Glaucous x Herring hybrid. With better and more prolonged views it was obvious that it was a very big male adult Kumlien's Gull, around the same size of the surrounding local Herring Gulls. The shots were taken at a distance, gulls ain't so easy to approach away from Nimmo's Pier!
Anyway this bird was on the darker end of this race/intergrade. The primary markings were a dark charcoal grey rather than black. The pattern is a near match to the adult bird that was in at Nimmo's Pier from January to March 2009, see the links below. This bird went slightly further beyond the 2009 individual in that it the band on P6 wasn't broken in the middle by the pale shaft.
It was a close match to Stage 5/the wing pattern N depicted in the "Identification and Variation of Winter Adult Kumlien's Gulls" by Steve N.G. Howell and Bruce MacTavish published in Alula 1/2003. According to the same paper this type accounts for only 4% of the Kumlien population.'s%20Gulls.pdf

Second-winter Kumlien's Gull

Had this second-winter Kumlien's Gull on the beach at Nimmo's Pier today. Weather conditions were dire and these were taken in the rain. It flew back towards the tip of the pier but I never saw it again.
Male Ring-necked Duck (presumably the returning bird), female Greater Scaup and a male Pochard x Tufted Duck at Loughrea earlier.

Lesser Scaup, Murlach

Murlach strikes again. In the last year now it's had American Coot, Green-winged Teal and Lesser Yellowlegs, amazing we you think it's had nothing in five years of coverage up until this time last year. I was doing the I-WeBS with the bossman Ger O'Donnell yesterday down at Ballyconneely. I picked up the American Coot while doing the same count here. While counting Murlach I had a female Tufted-type Duck out on the lake. I didn't have much time to eyeball it as we had places to go and birds to count but it did look interesting. I came back after finishing the counts but the light was nearly gone at this stage. After a lot humming and hawing I knew I would have to come back in the morning as I just couldn't make out the exact bill and on the two occasions it flapped it's wings I was at the wrong angle to properly make out the wing pattern. It spent most of its time diving so the head shape was very noticeable as it had crown feathers depressed in between dives for most of the time.
I spent two hours with the bird this morning. Again it spent most of its time diving in amongst the 27 Mute Swans present. There were times where I almost had myself convinced it was a Tufted Duck as the head shape again wasn't as eye catching while feeding. However the head shape was far more noticeable when the bird was relaxed or alert.
It approached to within 100 metres this morning. Even at that range it was still hard to make out the bill pattern in the dull overcast conditions. The whole bill was fairly dark grey which made examining the bill tip again tricky. It had a small black nail with some limited darkness bleeding either side of the nail but this doesn't seem too unusual for Lesser Scaups of this age and sex (see below). As it was the only diving duck present it was impossible to judge it's overall size. I don't recall ever seeing any diving duck from this site at all actually. It could be aged by the very dull eye and is most likely a female as a young male should show some signs of the sex at this stage such as new grey feathers to the upperparts or new black feathers on the head, neck or breast. Thankfully the bird eventually flapped after a spot of preening and revealed the classic Lesser Scaup wing bar consisting of clean white secondaries sharply contrasting with grey primaries. I had a Lesser Scaup-like drake Aythya hybrid in Clare last winter which had white on the secondaries and this continued onto the inner primaries while the outer primaries were grey.
The shots of the Murlach bird are only record shots taken at long range in poor light and are fully cropped but they at least give you an impression of the bird. Were this bird at longer range in with large numbers of duck for example at Lough Corrib it's entirely possible it mightn't have been picked out or clinched.

Head shape not very striking between dives.

More typical Lesser Scaup head shape.

This and the pic below show the distinctive wing pattern and even the head shape.

All shots below are from Florida taken in slightly better light and closer range from last winter.
