Thompson Water, Norfolk

Following yesterdays success at Thompson Water, I decided to pay another visit to check on the Hobbies.  The weather was fine, sunny, and warm, good conditions for this special raptor, I was not disappointed.

Hobby (one of 4) at Thompson Water 4th May 2014

2 Cormorant
Grey Heron
Coot
2 Common Tern (pair)
5 Black-headed Gull
4 HOBBY
1 MARSH HARRIER (female)
Common Buzzard
Reed Warbler
3 Garden Warbler (pair + male)
Blackcap
3+ Cetti's Warbler
Chiffchaff

A total of 4 HOBBIES were seen throughout the afternoons visit to Thompson Water.  These superb Falcons were once again hunting and feeding upon winged insects which were caught from either over the water or above surrounding woodland.  Now that we are in May the potential for multiple numbers of Hobby exists. I have seen 10 to 15 at this locality, however, will the day come when 80+ Hobbies are seen together, as they are, not too far away at Lakenheath Fen reserve.   
A female Marsh Harrier was seen, usually over the reeds where it hunted. I am intriqued that this raptor is spending some time at Thompson Water.
At least 3 Cetti's Warblers were in song, including one in Sallow next to where I was standing, this was an incredibly loud song, but could I see the bird, no I couldn't.
Strangely, there was not a single Swallow species or Swift over the water, I would expect good numbers at this and other localities by now, perhaps the recent northerly winds have held up their passage.
