Pitsford events

Hello

Today I undertook the last Common Bird Census of the season around the reserve at Pitsford Reservoir, starting at 5am this morning. An unearthly golden glow and banks of mist awaited and enthralled me as I meandered north of the causeway. Although it was pleasant temperatures right from the word go it didn't become hot and sunny until I was about half way around.

Being towards the end of the season this last session is all about mopping up on late breeders and seeing evidence of productivity rather than mapping territories. Even now though there were odd Robins, Song Thrushes, Blackcaps and Chiffchaffs still singing and holding territory but of course all the tits and many of the warblers, Treecreeper and Goldcrest offspring were gleaning the trees and bushes in large roving mixed flocks. Willow Tits were noted in the Scaldwell and Holcot Bays. Fresh-in migrants included juvenile Willow Warblers and a juvenile Grey Wagtail, and juvenile Sedge Warblers will be from elsewhere (none breeding on the reserve at all this year).

Great White Egrets were noted south of the causeway and in the Scaldwell and Walgrave Bays, probably just two mobile birds being involved in these sightings. Some fifteen Little Egrets were present as were nearly four hundred moulting Gadwall and reasonable numbers of Tufted Duck and Pochard. Kingfisher and Common Sandpiper added a little more variety and two eclipse drake Red-crested Pochard were today in the Scaldwell Bay. No doubt the summering Goldeneye is still there somewhere but I didn't see it.

Larger breeding birds included five broods of Mute Swan, two broods of Great Crested Grebe, four broods of Tufted Duck, three Common Buzzard families and two family groups of Sparrowhawk. 

The very warm conditions brought forth a host of insects which included 15 species of butterfly (perhaps the best being Purple Hairstreak) and 14 species of odonata which included Beautiful Demoiselle and another Lesser Emperor dragonfly. A fairly worn Hummingbird Hawk-moth showed well in the Holcot Bay.

The week of events celebrating fifty years of conservation at Pitsford Reservoir continues and there is an excellent free photographic exhibition at the Fishing Lodge illustrating some of the wildlife on-site including images from Robin Gossage and Dave Jackson (open 9.30am - 4pm every day up to and including Sunday 28th July). Weather permitting there will also be a bird ringing demonstration near to the Fishing Lodge on Saturday 27th July with a drop-in opportunity of coming along anytime between 8.30am and 12.30pm.
