Island Life

I opened the Tern hide to be greeted by a swarm of geese on the shore just to the east of the hide, they were mostly greylags which come to the lake to moult, the numbers are slowly building at present but there are probably many more to come.

It busy day today with the Lower Test volunteer team in for the morning to help me out by dealing with a difficult hanging tree that had resulted in the closure of the path between the Ivy North and Woodland hides. It took pretty much the whole morning to sort out, There were several stems to deal with and none of them fell straightforwardly to the ground requiring winching and rolling to get them down and safely cleared.There was a school in, so although the reserve was not busy there was lots of activity around the Centre.

Most fo the day was very grey and occasionally drizzly and I was concerned that our planned trip out to the island in Ibsley Water to ring some black-headed gull chicks might have to abandoned. Luckily at about four o’clock it cleared to a bright blue sky and the trip was on. We first put some rings on the chicks here last year, it will be interesting to see where they get to. This is a relatively new colony and it grew rapidly in the first two years but numbers seem to have stabilised somewhat now.

Most of the chicks we saw were large, in fact two made short flights to avoid getting caught. There were also quite a few nests with eggs or very newly hatched chicks, so the nesting seems to have happened in two waves.

The small chicks stay put on their nests, the larger ones seemed to have two strategies, either to run or swim for it or crouch down and not move. the latter makes them very hard to see, but easy to pick up when you do, running is great of they are fast enough to get away, but makes them easy to spot and catch if they are not. Some will always swim, which can be a problem if it is too windy or the wind is carrying them away from the nesting island, however this evening was ideal with a light south-east breeze, meaning they could swim away a bit, but would naturally be drifted back toward the island after we had gone. We probably caught about fifty, but missed many more, this is because lots were hiding in the deep nettles that cover much of the island.
