Blagdon Lake;
(Lead by Nigel Milbourne )
On this cool morning, fourteen of us met by the Dam at
Blagdon Lake. Sheltered from a stiff southerly wind by the Mendip Hills, the
lake was relatively calm, glinting under a grey sky. Many water birds were visible, predominantly
Coot and Tufted Ducks with the occasional Great Crested Grebe. Almost
immediately we were finding less common birds on the lake. While scanning
through a distant flock of Common and Black-headed Gulls, two Mediterranean
Gulls were spotted briefly and seen by a lucky few. Despite a determined search
and deploying several telescopes we were unable to relocate either gull. Then
we spotted an immature Peregrine Falcon flying down the lake, putting up the
gulls until these in turn began to mob the Peregrine!
Before moving our cars into the Bristol Water lodge car
park, Nigel Milbourne our leader for the day, showed us inside the old “venturi
house” to explain recent adaptations to promote bat conservation. Blagdon Lake
has been found to provide significant habitat for several bat species, including
the little studied Nathusius’ pipistrelle, which have been recorded advertising
from the “venturi house”. Other bats using the building include Brown
long-eared and Soprano pipistrelles. One significant feature of the “venturi house”
is a deep pit below, providing cave like conditions for bat hibernation.
From the lodge we walked the metalled track along the south
shore of the lake following various inlets.
A Black-necked Grebe with striking ruby red eyes has been
wintering on the lake for some weeks. Locating the bird from approximately half
way down the lake, we took some time for everyone to see the bird through a
telescope before moving on.
In the fields flanking the lake, we saw Starlings and
Redwings feeding on adjacent farmland, and with these just a few Fieldfares. A
flock of Lapwings flew up the lake. In wooded sections there were the typical
passerines including Goldcrest, Tree creepers and tit species, although many were recognised by call rather than sight. At
the eastern end of the lake we found wintering a Chiff-chaff. This is the shallow end of the lake which is
favoured by dabbling ducks, and we saw Gadwall, Shoveler and Teal.
Here we also watched several Snipe fly up from the reed-bed. Finally we visited the old fish hatchery,
with inlet stream Mistletoe clad Poplar trees and bird feeders, before heading
back to our cars along the lake.
