It was something of a shock to find myself scraping the ice
off my car on Saturday morning, when I left Johannesburg earlier in the week
the temperature had been 34 degrees! The moor had changed hugely in the three
weeks since my last visit. Water levels had risen and then it had frozen, the
hedgerows were rimed with frost and only reduced areas of the lagoons were ice
free.
The most obvious birds this weekend were the winter
thrushes. Still very flighty and garrulous they exploded from the hedgerows in
very large numbers. One flock on Sunday morning flying along the northern edge
of Greenaways must have numbered well over five hundred birds. Despite the
attention of the Fieldfares and Redwings there are still plenty of berries on
the trees. The birds appear to have favoured the darker haws rather than the
lighter red ones, we speculated that perhaps the dark fruits are more mature,
riper and are possibly more nutritious or digestible. At the rate they are
being consumed it will not be very long before even the lighter fruits are
gone.

The apple tree on the path to the second screen that has
carried such a massive crop this autumn still has some fruit on the tree and
the ditch below is absolutely full of windfalls. The Starlings are taking
advantage of the way the frost has softened the remaining fruit and are feeding
on them greedily with considerable competition for the best perches. We hoped
that there might be a few left should the expected Waxwings make it down this
way.
Raptors were also much in abundance this weekend. There are
two Peregrines being seen regularly, a large mature female and a smaller
probably juvenile male. One of them was seen to snatch a Starling from the pre
roost display on Thursday afternoon. The two distinctly different Marsh
Harriers were seen from time to time over and around the reedbed. For over an
hour on Sunday morning one of them, probably a juvenile perched just a couple
of feet up in the reeds directly out from the first screen where it could be
seen preening and simply loafing about. Two Hen Harriers were also noted, on
Sunday one of them was pursued all along the northern edge of Greenaways by a
Kestrel. It was difficult at times to work out who was mobbing whom, as they
seemed to alternate in the role of aggressor. Red Kites and Buzzards were
common, one Buzzard with a great deal of white on it attracted particular
attention. I have not heard of any sightings of Merlin but this doesn’t mean that
they are not here anymore. They certainly range far beyond the edges of the reserve
out onto the MOD land and beyond.

Bitterns are now regular and it would be unusual not to see
at least one on a visit. We were particularly lucky on Sunday when we saw at
least three individuals from the second screen. For a short while two could be
seen standing on the reed margin only twenty metres or so apart. When the birds
meet as two did on Thursday, there is a great deal of threat and bluster with
feathers fluffed up and a lot angry posturing. It is of course impossible to
say whether these birds are “our” breeders or indeed their offspring. Many
Bitterns come over from the continent to winter in the UK.

On Sunday as the frost melted in the sunshine there were at
least thirty Snipe probing around the tussocks on the Closes. It must have been
the only place that they could feed, frozen ground must be a particular
challenge to long billed birds that rely on probing for their food.
Two new species were added to the Otmoor year list while I
was away, the Ring-necked Parakeet that was in the Starling roost over a week
ago and last week a Water Pipit that was found on Big Otmoor. This brings the
annual total up to one hundred and forty nine species a shade under what we
recorded last year, however there are still three weeks to go in 2016 and according
to those in the know the Waxwings are on their way!
Very many thanks to Steve and Pete Roby who with Badgers
help kept the blog going while I was away.
