Heron at the Hamlet

Over the past week we have seen a Heron flying above the Hamlet on several occasions. As none of us at the Hamlet know much about Heron, we decided to look it up

We believe it was a Grey Heron - white with black markings on head and neck.

We looked up some information:

Length: 90-98 cm (36-40")
Wing Span: 175-195 cm (70-78")
Weight: 1500-2000 g (3½-4½lb)

Description
The Grey Heron is a tall bird with a long neck and legs, and a heavy dagger-like bill.
The upperparts are grey, but the head, neck and belly are white. The crest is black and black markings continue down the throat to the belly.

In flight, the outer half of the wings are black and the wing beat is very slow with the neck retracted into its shoulders and the legs are extended. In or near water, they are often standing motionless with their head in their shoulders or feeding alone. Juveniles are darker with much less white and lack the long crest plumes.

Feeding
Grey Herons eat mainly fish, amphibians and small mammals, and occasionally birds.
They are solitary feeders and very patient, and will standstill for long periods stalking their prey. They will quickly empty a garden pond of fish.

Nesting
They nest in tall trees and usually with other herons to form a colony or heronry. The nest is a large platform, made from twigs and grass, and built by both male and female birds.
The duties of incubating the eggs are performed by both parents. The eggs are about 60 mm by 43 mm, and pale greenish-blue. Both adults feed the young birds.

Movements
British herons are mostly sedentary, but some do migrate to Ireland and the near-continent, such as France and Holland. In the winter, northern European Grey Herons arrive in eastern Britain, especially along the coast.

Conservation
Illegal persecution and pollution are less of an issue today than a few years ago and the population is still increasingly slowly.
