Over the past 2-days the chicks have changed phenomenally. They now all have typical black caps, yellow breast feathers and a central black chest strip.
Both Mrs and Mr GT have been run-ragged feeding the 3 Amigos who will probably fledge sometime within the next week. It is amazing how the whole process from hatching to fledging only takes about 3-weeks. Although the chicks have grown feathers these are only 'starter' feathers to enable the chicks to fledge the nest quickly. The quality of starter feathers is quite poor so they'll be replaced over the coming summer and autumn with adult feathers through moulting.
According to the BTO website (http://blx1.bto.org/birdfacts/results/bob14640.htm) the survival rate for juvenile GTs is only 38% in their first year. There is also a measurable decline in brood size over the past few years but this years 3 is very low and we do wonder whether this is a result of last years poor breeding season.
