Titchfield Haven - End of Season Update

The ringing season is now all but finished for us at the Haven, although there may be the odd session to target certain priority species. Overall it ended up being a pretty good season, which was not immediately apparent at the start of the season. A total of 3960 new birds were ringed of 38 species, a further 177 birds were retrapped or controlled, a handful of the resident species, several times.

The anticipated eastern mega turned out to be a Barred Warbler, which for many counties is a regular vagrant, but not for Hampshire, where it was the first ever ringed in the county. The total is a little misleading in that it shows two birds being caught, but that is due to it being retrapped two days after the original capture, fortunately for me. Other highlights include a Wryneck, our 3rd ever, Tree Pipit our 8th ever and our first ever Grey Wagtail for the site. It was surprising not to catch a Yellow-browed Warbler this year, given how many were recorded on the east coast, but the expected record total of Goldcrests did materialise. A total of 158 new birds were ringed, beating the previous best total by 49, a couple of controls were also trapped, so the actual total of birds not previously trapped at the Haven will be 160. Other new high totals included Lesser Redpoll, with 23 new birds ringed, and Blackcap with an amazing 973 new birds ringed, well above the 495 average.

I have previously posted about the selected species comparisons, so there is no need to cover that ground again in detail. So to summarise, the Grasshopper Warbler total remained low, with only 135 new birds ringed and well below the average of 264. The Sedge Warbler total also low at 799 new birds, again will below the average of 841. By contrast however, the Reed Warbler total was well above the 459 average; the Willow Warbler total was also above the 125 average. Whitethroat, Chiffchaff, Cetti's Warbler and Robin totals were also all above average.

Our sixth year without an Aquatic Warbler is setting a very worrying trend.
