No equivalent 2017 session
Recaptures: (04) recent except:
Cetti’s Warbler ringed 27-Aug-2016
Chiffchaff ringed 03-Jun-2017
Long-tailed Tit ringed 04-Oct-2015

Sightings 43 Species: Ian’s list, no Sedge Warblers, on the reed bed, this week, just the single Reed Warbler, a couple of Reed Buntings and two or three calling water rail. One of the local Ravens was quite active stirring up the crows as it flew around calling. Two Oystercatchers also flew over calling, two of several reported locally this weekend. A nice end to the morning was when my first Cuckoo of the year flew over calling as I carried my equipment back from the reed bed.

13/04 Greenham Common

After a walk round the common Thursday produced two Ring Ouzels and a Wheartear so I thought I'd try playing audio lures of them at the western enclosure today. I put up the usual three nets from 08:00 to 10:30hrs with IW and RJC. Needless to say we didn't even get a sniff of either species. Just the usual two birds processed, a blue tit ringed as a pulli on the 09-May-2017 at a nearby Sandleford Copse nest box (A8) and a 09-Jul-2017 ringed Goldcrest. It was a very dark almost twilight morning so when we heard Owls it was not that surprising. We were just about to add to our bird lists when we realised that one of the Iplayers playing Ring Ouzel on repeat had defaulted to sequential.
27 species detected, three Herring Gulls and a couple of Swallows the best  birds

Location: Thatcham Marsh LNR
Session: 08-Mar-2018 07:30 to 11:00hrs
Headlines: The rainy weather just missed us apart from some spits and spots towards the end of the session. We had quite a good session including the first Sedge Warbler of the season. Only a few birds showed signs of coming into breeding condition. One good round of seven birds otherwise just two or three each check. Last year’s equivalent had a similar total but included more migrant species more confirmation that this year is a late spring.
