Opportunists

Whilst gulls are are well known for their sometimes unsavoury habit of scavenging from our waste, they are in fact highly opportunistic feeders with a varied diet ranging from fish to insects, worms, crustaceans, molluscs and even other small birds and their eggs.

High tide in the harbour provides the resident Herring Gulls with a regular and constant supply of natural food. On this particular day, crab was on the menu.

Casting a beady yellow eye over the water from it’s nearby vantage point, this adult herring gull suddenly took flight and swooped down into the water headfirst, emerging seconds later with a large crab clamped in it’s beak.

The large crab struggled frantically as it was caught, flailing free from the birds beak and turning on it’s attacker with snapping claws.

The gull jabbed at the crab with it’s powerful beak and seized it by a leg before shaking it vigorously in an attempt to disarm it. Only after repeated attempts and the loss of several limbs did the crab give up the struggle.

Once the gull had satisfied it’s hunger it flew off, leaving behind bits of empty shell shattered on the ground. Having patiently waited at a safe distance, a flock of Jackdaws soon swooped in to clean up any leftovers.

The Jackdaws seemed particularly keen on their seafood supper, and there was much angry chattering and raised feathers as they bickered over the remains.

This particular Jackdaw appeared to have an old healing injury to it’s head, possibly from a scrap with it’s fellow birds of perhaps a narrow escape from a predator.
