A relatively short but productive visit to Thompson Water. Wildfowl were present in good numbers with Mallard being the most numerous species with 150+ birds present. Other wildfowl included a few Shoveler, Gadwall, 5 Mute Swans, and rather interestingly, a single ♀ Pintail.
Two Marsh Harriers were seen (♂ and ♀), the ♂ being readily identifiable by his smaller size and tri-coloured plumage. Also present was two Buzzards.

The highlight of this visit to Thompson Water was watching at least two Hobbies hunting, catching, and feeding upon insects. These supremely fast Falcons fly low and close to the Water Soldier where they would chase insects, sometimes displaying incredible manouvers in the chase.
Typical behaviour was seen as in picture (1) where a Hobby would make frequent passes over the Water Soldier. Picture (2) shows a Hobby in a fast pass, this is a juvenile bird, it's age confirmed by the pale tips to the wing coverts and on the rump. The Hobby in picture (3) is turning sharply, possibly having seen an insect to chase, this is a useful angle for ageing this bird as it has pale buff undertail coverts, on adult birds the undertail coverts or 'trousers' are red. Finally, as shown in picture (4) the Hobby has an insect in its talons upon which it feeds on in flight.
Once seen, as in this observation today, the supreme velocity in the chase and stoop by Hobbies is mesmerising and totally unforgettable as they chase and catch insects and small birds which include Hirundines and even Swifts.
The Hobby is a migratory Falcon arriving with us in Britain in mid-April, they are scarce but increasing breeders with us. At the time of writing, Hobbies will be preparing to migrate south, most would have departed now and by October all birds will have left us for their wintering grounds in south-central Africa.
