Song Thrush young

Quick post tonight. As well as extracting more data from the nest boxes today I had a Wren nest and three Song Thrush nests to check. The Wren was fully clutched on 4 eggs, the first egg date being 23rd April, two of the Song Thrush nests had fledged their young, 1 and 3 chicks respectively and the third nest still has 3 young at the feather stage of FS. The nest was found by cold searching an area where a Song Thrush was seen flying from and the nest is situated at about 4m high in a hollowed out part of a tree trunk surrounded by ivy. A good well hidden nest and the images are below (only two of the three can be seen clearly) -
