24/05 Greenham Common

Location: 24/05 Greenham Common Western Enclosure
Session: 24-May-2017 06:45 to 10:20hrs
Headlines: Quick session although I nearly didn’t go as there was a bit of a blow in the treetops at home. It was misty when I arrived with an occasional swirling breeze. It soon cleared to a sunny day, hot late morning. Not much bird movement though until a flock of Long-tailed Tit crossed the heath; captured five all juveniles and probably missed an equal number. Was hoping to use up seven A rings left over from ringing pulli but the Blue Tit was a retrap so I only used two on the Bullfinch and a long winged Great Tit. It had an 82mm wing. This was queried by the database as 81 is the recorded extreme; glad I checked it. A nice juvenile lone Coal Tit also crossed, seemed a bit young to be unaccompanied.
The nest box breeding season was about two weeks earlier than most years, the third and last week of May is normally peak pulli ringing time. I have ringed all my boxes and so am able to do a few general ringing session at the end of May for a change.
Weather: Misty and breeze early, calm, sunny. hot and clear later
Present: JL, IW
Nets: 48M in three rides of 18M, 18, 12M up from 07:00 to 10:00hrs

The Long-tailed Tits and the Coal Tit were juveniles the others were full grown
Recaptures: Blue Tit from the 11-Apr-2017
 Juvenile Coal Tit
The long winged Great Tit with an 82mm wing and a heavy bird at 20.3grms

Sightings 39 Species: Interestingly no Blackcap or Wren heard or seen during the session. Probably the best (unexpected) birds seen, two Rooks over. As mentioned above it was quiet with occasional singing by most other warbler species. It was nice to see a family party of Stonechats included some ringed juveniles. I had hopes of capturing a Starling or two as there are good numbers of juveniles over the common. When I arrived there was a family party in the enclosure but they flew off. Also, the House Martins were collecting mud in the nearby puddle and managing to avoid the nets as they made their approach.

22/05 NEST BOX CHECKING 2017

A final check of fledglings yet to be ringed cleared the last three outstanding nest boxes. One nest box on Boxford Common had 5 Blue Tit pulli including 1 runt and 2 Great Tit pulli in the same nest; generating shared nest records.
All that is left to be done  this year is to check how many fledged from each nest box, probably try and check mid-June but usually end up waiting until Oct/Nov due to other priorities.

21/05 Thatcham Marsh LNR CES Visit 2017.03

Location: Thatcham Marsh LNR CES Visit 2017.03
Session: 21-May-2017 05:30 to 10:30hrs
Headlines: I overslept and arrived a bit late, fortunately the nets went up without a hitch and got me back to time more or less. It was slow for the first half and the reed bed was noticeably quiet with relatively few Acrocephalus singing.
54 in the standard nets is the best ever for visit 3, well above the average of 35 range 2002-18, and previously 1993-51 was the highest total. We captured 16 Long-tailed Tits in the second half of the session that push the total up. Sedge Warbler with a capture of 8 was one below the average of 9, while 18 Reed Warbler is one above the average for visit 3. For both species the cumulative total is above average. After Cetti’s Warbler singing all around the nets and not being captured on the last visit we capture 5 this time. We rarely capture Jay here these days, we manage to extract and ring it only got minor injuries. As is often the case the capture of a Long-tailed Tit flock makes a big difference although without them 38 is quite a good total for the standard nets. All but two of the Long-tailed Tit were juveniles, quite early this year. 

Weather: Some sunny periods, often overcast, cool but warm when in the sunshine., calm
Present: JL, IW, JHW, DL, JPM, GB, SC
Nets: 256metres in four rides: standard nets, one reed bed ride of 108+90M, additional nets: three scrub rides of 18M, 18M and 12M up from 06:05 to 10:10hrs

Recaptures: (27) Blackbird 210d Cetti’s Warbler 3y 290d, 2y 228d, 1y 265d, 267d Chiffchaff 250d (ringed at Greenham Common Sep 2016) Long-tailed Tit 245d Reed Warbler 2y 5d, 1y 329d 364dx2, 351d, 322d Wren 322d; others recent.

Sightings 49 Species: As I was putting my nets up a Buzzard flew west harassed by two crows. A few minutes late it return being buffeted by a Raven and the two crows with a Magpie not far behind and another two crows flew over to join in, having a bad day or what. Two Great Crested Grebe flying fairly high west, an unusual sighting. The substantial flock of Long-tailed Tit circulated from early morning until many were captured. Should be getting a lot more noisy soon as more juveniles fledge.
