Lots of juveniles

There are lots of juveniles around at Fleet Pond this morning. Many have just left the nest including this robin. Young birds grow their first feathers really quickly as they are at most risk when in the nest so need to get out quick. Once the birds have left the nest over the first few months they start their post juvenile moult. Most birds only moult some of their juvenile feathers. The robin will moult out his spotty breast feathers and greater covers but will keep its primaries until after breeding next summer.
