I have already reported about the good productivity of our nest box schemes, now our ringing sessions provides further proof . A further visit to Jerry and Barbara's garden brought the total Great Tit catch for the month to 81 which compares to last years total from August to April of 85! Blue Tits were 91 compared to 153 in the whole of last season. Great Spotted Woodpeckers an amazing 21 one short of last seasons total and Bullfinch 24 last month compared to only 21 last year. All proof of an excellent season with almost all of these birds being juveniles.
At our reed bed site at Leighton Moss because of poor weather we visited in July on four less occasions than in 2012 but allowing for this Willow, Sedge and Reed Warblers are all well up as are Blue Tits. Blue Tits are interesting, the percentage of adults in last seasons catch was17% this year it is only 2.5% a sure sign of good productivity.
Just got the results of our Pied Flycatcher RAS in the Lune valley. We ringed 483 nestlings which is 163 up on 2015 even though the breeding population was ca 10 pairs lower this year. and there was high predation at two sites.
Will be interesting to see if this good productivity results in good ringing catches as the season progresses .
