LBB counts 2019
( aka Skomer pilgrimage, aka finding rare birds)
We are very privilaged to once again be asked to guest
blog of our venture to Skomer to count the Lesser Black-backed Gulls.
We arrived on May 16th, having just missed the
Woodchat Shrike which was a shame, but after all we were here to count gulls,
not find rare birds …………
So we met the wonderful new wardens Sylwia and Nathan
and were reunited with friends from previous years and indeed met some new
ones, all wonderful people.
After throwing our stuff out of the rucksacks and
stocking up the ‘day bag’ with loads of calories that we knew we were going to
need we were off counting. The wind was still in the south-east where it had
been for a few days, so we were hopeful of a rarity from Europe.
The first few hours were uneventful, but there was a
steady trickle of hirundines going west and of course it was fantastic to see
the islands residents like Chough, Razorbill, Oystercatchers etc, and see the
kittiwakes coming to Moorey Mere to collect material to build their nests.

Counting LBB’s
So just a brief idea of what we and the island staff
do to count the gulls.
The whole island is one colony of LBB’s , it is then
divided into sub-colonies which stay the same each year with minor fluctuations
in size/ shape, then there are fixed points to view each sub-colony from. Ted
and I go to those fixed points and count how many birds are actually on nests/
nesting, these are called the eye counts. Within the next week the island staff
visit selected colonies and by conducting a quick walk through establish
exactly how may nests are there, invariably a few more than we saw. This gives
a correction factor which is then used on the whole count from all the eye
counts to establish the size of the whole colony.

Early morning saw a female Bar-tailed Godwit fly into
North pond which is a good bird here, then Ted and I were at North Valley
bushes when the orange flash that was in fact a Turtle Dove whizzed past us –
another great bird, and one that Ted had been hoping for. Unfortunately this
was not to be seen again.
The Saturday saw the return of another island ‘mega’,
the House Sparrow had returned to the farm, as mad as it might sound until this
bird I’d seen 3-4 House Sparrows here and I’ve been coming for 34 years !

In the evening Ted’s sharp eyes produced a couple of
interesting gulls at North Pond, one a LBB X Herring hybrid, which is possibly
the bird being reported as a Yellow-legged Gull and a really interesting LBB
with a streaked head. It just goes to show that looking at all these gulls fine
tunes your skills in seeing something different.

Sunday 19th was our last morning, we had
half a day and had pretty much the same area’s to still count as our last
morning last year. Last year was interrupted by the appearance of a Subalpine
Warbler.
We went to the first count point where Ted had been
itching to get to since we arrived as next to it is the biggest bush on the
island. I was merrily counting away when Ted said – ‘There’s a Turtle Dove
sitting on the wall in front of us’ – Boom !!!! We could see Nathan, Sylwia and
Clare at the CES ringing site, but before I could ring them the bird flew and
landed on another wall, I made the call and they all locked their bins on the
spot where it was and then it flew again- they all got it. Incredibly it then
flew straight into the bushes at the bottom of North Valley where the mist nets
were………….surely we couldn’t be that lucky ?
We saw where it went in, then I looked at Nathan/ Sylwia and Clare- they
were already on the move, a few second later the phone was ringing……………………….. surely
not ?
YES !!!! Back of the net !!
The dove had flown straight into the mist net-
unbelievable. The incredibly beautiful, and now sadly very rare bird was ringed
and released where it flew off strongly back to the area where Ted first found
it.

Once again an amazing few days, with amazing people,
brilliant birds, a few thousand gulls on what is to me, the most beautiful
place on planet earth.
