Last week developed a Goshawk theme. A day in the Brecks on one of the few warm
spring-like days so far resulted in some opportunistic top-of-forest watching,
with views of a displaying pair in a regular location. Largely a bird of big
forests, Goshawk has a small but increasing population in Thetford Forest with
eight pairs located by regular observers last year. I then departed for a couple of days in
deepest Wales, where despite deteriorating weather, I was lucky enough to see
another couple of birds. The first was a
male flushed from a woodland ride early in the morning. It weaved its way heavily between the trees carrying
a lumpy prey item which appeared to be a crow.
Landing in a small copse ahead of us to pluck the bird, we crept forward
hopeful of a reasonable view, but typically it vanished in a couple of wing-beats,
taking its breakfast with it. Later, it
or another male was displaying over the woodland, pinpointing a possible nest
site. Two UK studies have shown that
crows and pigeons make up the bulk (around 68%) of the diet of Goshawks during
the breeding season. This is similar to
the diet of Dutch birds but different to those in Scandinavia where grouse make
up a bigger percentage of the prey. The
Goshawk has little competition in the UK.
Peregrines are closest in diet but Goshawks are more versatile; taking
prey in wooded landscapes and from the ground.
Locally in the Lee Valley area, I have
only managed a paltry three birds in 40 years of birding, and one of those had
jesses. Even four years of living in a
house overlooking Epping Forest, where they are regularly claimed, resulted in
nil sightings. The aforementioned bird with jesses; at Amwell in 1988, memorably
took a Wood Pigeon with some force in flight, turning the pigeon into a
firework explosion of feathers in the sky, followed by the gently descending
feathery sparkles after the birds had long gone.
