I
have been putting plenty of seed down at the feeding stations at Longshaw and
Haigh during the week and made some additional feeders to ensure there is a
continuous supply of seed. The large capacity and design of the feeders should mean
they will only need refilling a couple of times a week although that could
change if the number of birds continues to increase. When I went to put food
out on Thursday there were good numbers of finches present including 30+
Bramblings at both sites so I was keen to try and fit in a ringing session at
each over the weekend, weather permitting.
This
morning looked like being the only decent opportunity for ringing with a forecast
of heavy rain and increasing winds from late Saturday afternoon through to
Sunday morning. I decided to go to Longshaw as there was also the chance of
luring a Waxwing in again although expecting a repeat of last week was a real
long shot. I met up with John G and we had 3 nets up before first light, one
60ft and two 30ft nets. I also set up a couple of MP3 lures players playing
Waxwing on the off chance.
Bramblings
and Chaffinches started dropping in shortly after first light but no Greenfinches. For some reason Greenfinches only start to arrive about an hour or so
later and peak numbers are only present from around mid morning onwards. I am
not sure why there should be such a difference in arrival times between these
species but it is very noticeable. The distance from their respective roost
sites could be a factor but can’t really explain such a big difference in
arrival times and the even later build up in numbers of Greenfinches. They may
simply leave their roost sites at different times but that would seem strange
for similar species with the same diet. Anyway there is always something to
learn and that is what keeps my interest.
The
morning progressed in a steady fashion but with fewer retraps than might be
expected given the number of birds ringed last Sunday. At around 9:30 a single Waxwing
turned up but history didn’t repeat itself and it wasn’t caught. On the next
round of the nets 2 Coal Tits were amongst the catch of finches which is not that
unusual but one of these birds was a control (ringed elsewhere); ring number
starting Y99. There has been an eruption of this species in the UK this autumn so
it will be interesting to find out where this bird has come from. Hopefully it
will be more than a local movement.
We
packed up at around 11:30 having caught 62 new birds and 16 recaptures. Finches
dominated the totals with 22 Brambling (including 3 retraps), 20 Chaffinch and 19
Greenfinch.
The
sky had greyed during the morning and the wind was still very light so I
persuaded John to give Haigh a try in the afternoon before the rain arrived.
After a quick bite to eat we drove up to Haigh and put up a couple of nets. The
breeze was picking up but this was offset to some extent by it being very dull
and overcast.
Afternoon
ringing sessions are usually much less productive as birds have had all morning
to feed up and there is usually more wind making nets easier to see. There were
a lot of finches present on arrival with over 60 in the vicinity of the feeders,
mainly Bramblings and Greenfinch. Two Blue Tits were caught in the first net
while the second was being put up getting us off to a very quick start.
Bramblings
dominated the subsequent catches and made up a third of the afternoon’s total
of 75 birds. One of these Bramblings was a control (ringed elsewhere); ring
number starting D170. This was aged as a first year bird and will have been
ringed relatively recently because of that; possibly as a newly arrived migrant
on the east coast. The first spot of rain arrived shortly after 15:30
curtailing a very productive 3 hour afternoon ringing session.

Adult male Brambling left and first winter male Brambling right. Note the more extensive orange across the breast of the adult and the narrower and less extensive pale fringes to the head feathers. |
The
total for the day was 153 birds, comprised of 107 new birds and 46 recaptures.
Bramblings made up nearly one third of this total with 43 new birds, 3 retraps
and 1 control. This brings the number of Brambling ringed this autumn to 80
which is an exceptional total for us this early in the season. Anyone who has
read my last few posts will know that Bramblings have featured in one way or
another and that looks set to continue on today’s performance. Most of my
ringing effort will be at these two baited sites until next spring so I am
likely to become a real Brambling bore judging by recent performance. Such
events don’t come around very often and I will happily bore you with many more
Brambling related posts given half a chance.
