A weekend of two very different days. Saturday grey, drear
and eventually very damp and drizzly. Sunday was in complete contrast. It
started cold and frosty with just a hint of low mist as the sun rose orange through
the bare branches of the Roman Road oaks, a bright sunny morning followed.
Birdwise not too much has changed since last week. Bitterns
are once again showing frequently. On Sunday we saw two different individuals,
one flushing from the ditch beside the bridleway and flying out into the small
reedbed in the middle of Greenaways, the other coming from a small ditch on the
closes and flying across to land in the reeds on northern edge of the field.

The hide is offering plenty of interest from the finch flock
feeding on the seeds alongside it, this flock is getting bigger all the time.

When
we arrived back at the hide on Sunday morning after a visit to the screens we
wondered where all the birds had gone. Then we noticed a male Sparrowhawk
sitting motionless on one of the fenceposts…..as well as offering feeding for
the smaller birds it also creates a feeding opportunity for raptors!

Out at the screens the ducks were concentrated around the
small unfrozen leads of water but by mid-morning most of the ice had gone.
Wildfowl numbers are still significantly below those that we would expect at
this time in the winter. Water levels are still below target after the dry
autumn and early winter and this will be significant a factor.

Along the trail to the second screen there was a party of
eight or so Bullfinches feeding on the desiccated blackberries that are still
clinging to the brambles. It seems extraordinary that enough sustenance can still
be found in these tiny seeds.

Despite the cold we heard three different Cetti’s
warblers calling from the reedbed and the ditch beside the bridleway. A Short-eared
Owl was seen last week hunting across Greenaways in the mid-afternoon.

The most significant change on the moor over the last two
weeks has been the collapse of the Starling roost. Numbers fell from
approximately fifty thousand birds last weekend to barely five thousand by
Friday, the numbers halving daily. Please let anyone you know who might be
considering a visit that the spectacle is over now until the autumn. We don’t
fully understand why this has happened, but it may well be to do with the depletion
of feeding opportunities in the surrounding countryside. It will have a
positive effect on the health of the reedbed and the quality of the water in
the lagoon. To improve the water quality the RSPB are circulating the water out
onto Greenaways to dilute and dissipate the chemical effects of all those
starling droppings every night.

The raptors attracted by the roost are still present,
however. There was a report of a ring-tailed Harrier yesterday and a Merlin was
seen chasing a Snipe across the MOD land. Peregrines are attracted by the Lapwing
and Golden Plover flocks and Kestrels are drawn by a healthy population of
small mammals. The regular pair of Marsh Harriers are still haunting the
reedbed sometimes spending long periods of time perched in bushes surrounding
the lagoons.
