Mediterranean Gulls have returned to Tern Island, Moor Green Lakes, Berkshire and the good news is that a pair have held territory and are nesting.
In total six  have been seen, adults and first summer birds alike together amongst the large colony of Black Headed Gulls. Only one pair have paired, the others come and go.
Fingers crossed that they are successful in rearing a brood.

During the month other notables were, Greenshank, Cuckoo, Sedge Warbler, Reed Warbler, Garden Warbler, Whitethroat, Common Tern, Redshank and Mandarin.

 A Swift tower was erected at Moor Green Lakes a couple of weeks ago which is great news for the reserve, all we need now are the Swifts, which should be arriving in the next few weeks.

Quite a number of birds seen during March are now looking very handsome in their full breeding plumage. of note were a pair of Grey Wagtail which looked immaculate. All but a few of the many Black headed Gulls at Colebrook Lake North are sporting their brown hoods and the noise level of the gull colony at Tern Island has slowly got louder as the month progressed.

At the New Workings end of the reserve Shelduck numbers increased to five, whilst a Lapwing was seen to be nesting.  Little Ringed Plover have arrived, hopefully they will have another successful breeding season. 

Chiffchaff are now singing throughout the reserve as are Great Tit. Oystercatcher are back at Colebrook Lake North, where they have bred successfully in the past few years.
