05/08 Greenham Common Western Enclosure

Location: Greenham Common Western Enclosure
Session: 05-Aug-2016 06:30 to 10:10hrs
Headlines: The morning started slowly with no captures after putting the nets up. The audio produced Garden Warbler, Blackcap and Willow Warbler on the second round of the day. This was followed by a round that included the Blue Tit, a Reed Warbler (the fourth here this season), Robin, Garden Warbler, Willow Warbler and the first Whitethroats. It became apparent when extracting for this round that there was much activity in the surrounding bushes particularly to the south of the enclosure. The most obvious species was Whitethroat with other sylvia warblers. One of the Ipods was turned over to playing Whitethroat and another to Lesser Whitethroat. The next round consisted of mostly Whitethroat but also included a Meadow Pipit. As we approached one net two larger birds were captured at the far end of the net. As we got closer one pulled away from the net and released itself and as a consequence we ended up with one Woodlark instead of two. We were convinced it was a juvenile but wavered a bit when we notice it was in primary moult; a quick check of Svensson confirmed that both adults and juveniles have a complete moults at this time of the year. No Lesser Whitethroats materialised and the Dartford Warblers and Stonechats evaded the nets yet again as did some low flying hirundine. The was still plenty of activity in the surrounding bushes as we took the nets down but had to go somewhere so left promptly, otherwise would have stayed longer.
Weather: bright, sunny cool early warming up later, calm with an occasional light breeze
Present: JL, IW, RJC
Nets: 48M in three rides of 18M, 18M, 12M up from 06:35 to 10:00hrs
Lure (audio): Blackcap, Chiffchaff, Firecrest, Goldcrest, Willow Warbler, Linnet, Redstart, Dartford Warbler, Whitethroat, Lesser Whitethroat intermittently.
Capture (New/Recapture) 32 (29/3): Blackcap 2/0, Blue Tit 0/1, Chiffchaff 3/0, Garden Warbler 5/0, Goldfinch 1/0, Meadow pipit 1/0, Reed Warbler 1/0, Robin 1/0, Whitethroat 7/1, Willow Warbler 7/0, Woodlark 1/0.
Recaptures: 3, all recent, the Blue Tit was a female trapped in nest box PK32 on the 2nd June and the Whitethroat had been ringed on the last visit, while the Robin had been ringed here as a speckled juvenile 45 days ago and was now in full adult plumage.
Age Range: all 1st CY (calendar year) except the adult Blue Tit

 This Red Admiral soaked up the early morning sun for well over 30 minutes before flying off
Today's Woodlark a bit tidier than the full grown captured earlier this summer.
 
Sightings 36 Species: Early it was quiet but quite soon there was a lot of activity in the bushes, mostly Whitethroat and fewer Garden Warblers. As I was putting up the nets something called that made me think for a minute before realising it to be a Yellow Wagtail. There seems to have been a change in the resident Stonechats as none of those seen appeared to be ringed. A Kestrel flying just above the tree line also produced the Swift seen in the background; may have been more but they quickly disappeared. The overflying Sand Martin is a scarce species for this site. There is still a large flock of Goldfinch mostly near the cattle feeders. Linnet numbers are reduced most are ground feeding on the grass seed heads. The best bird of the day the Spotted Flycatcher spotted in the nearby birch trees by IW. Later it flew high over the enclosure south.
