3rd July 2013 Neville has gone.
Both parents were at site N this morning but there was no sign of Neville. At 16 days old, Neville would have been capable of "fledging" but the presence of both parents means that either predation or bad communication was responsible.
In guillemots, the chick jumps to the sea before it can fly (giving them the name 'droplings'). The male parent accompanies the chick for the first two months of its life at sea. During this time, the chick learns to fish for itself and the adult is flightless during its moult. Jeremy Greenwood studied the fledging of Lundy's guillemots in July 1962. With a fuller study on Handa (Sutherland, Scotland) he concluded the most fledging deaths result from chick and adult failing to meet each other on the sea. (Greenwood 1964).
On the positive side, another chick hatched today. Chick R (Rene) received a feed. There were 7 other feeds: Eleanor and Harman each received 2 feeds, and there were singles feeds for Bevill, Grenville, and Irwin. Christie, Qawser and Stanley were also seen today.
The weather forecast is looking good for the next few days - I'll try to keep you updated. More chicks should be fledging...
