2018 - RB2 Visit 1 and CES Visit 5

Jerry was in RB2, for the first Reed Warbler RAS session. Fortunately the horse flies and mosquitoes that were around when he prepared the net lane last week, seemed to have dispersed. The catch was 27 + (17), the best of which were a male Pied Flycatcher (presumably from one of the boxes), and two juvenile Redstarts (not from one of the boxes). The total was even better considering that the late spring has meant that the reed is currently only about half the height of the nets and is usually far more advanced when we start the RB2 RAS sessions. Four Reed Warbler retraps kick started the RAS and the lack of juveniles indicated the later than usual breeding season in the reed beds.

Peter was in the Scrub, with Alan and Ruth doing the CES, his day was much quieter which, despite his disappointment, this isn't all that unusual. The numbers for recent years were: 2017 - 64, 2016 - 20, 2015 - 62, 2014 - 16, 2013 - 38, 2012 - 28. Peters total catch was a total of 10 + (6). We think the large capture range for this CES visit can be explained by the timing of the breeding season - few chicks are fledged by early June during late seasons, giving lower capture totals some way below the average for this visit.

He recaught the 'most local' Cettis Warbler pair, the female caught for the first time this year and the male who has again extended his longevity record for the group (see more detail from 6 weeks ago HERE). For the second CES in a row a control Blackcap was caught, details will emerge in the future of that birds original ringing site.

Day Totals were as follows:

Species Totals
Treec 2
Wren 1 (1)
Robin (2)
Redst 2 (1)
Piefl 1
Garwa 1
Reewa 6 (4)
Blaca 2 (2)
Cetwa (2)
Bluti 7 (7)
Greti 4
Chaff 1
Reebu 4 (1)
Bullf (1)
Grefi 1
Dunno (1)
Sont 3
Blabi 2+4p (1)
Totals 37+ 4p (23)

after about 30+ years, the reed area between Gn5 & Gn6 was being taken over by bramble, so Alan L did a trial cut in April, to see how it regenerated.

The results so far are very promising!
