The Peregrine chicks are on the verge of fledging.  The wing flapping is hitting new high levels of activity and at least one of them will fledge in next day or so!  Spotted all 4 chicks today and was able to ID at least two sets of leg bands.  The leg bands show two digit numbers with two digit letters.  In both cases the leg bands are black over green colors.  All traces of down are gone at this stage of growth.  Terrific series of 20 clear and close photos in excellent light conditions of the 4 peregrines chicks in the final pre-fledge stage of growth!
