Three of the chicks were much more advanced and left the nest some time before the final ones did. They came back for a feed though on one occasion I saw, emphasising the difference in progress.

Yes possibly from different broods, although if they were nearby to each other and the known nest, which the location suggests, I suggest no doubt (OK not a lot of reason to doubt) of the same family often reported there recently. When I observed them on the day they left the nest (although that leaving may well have been over several days), there was noticeable difference in the stage of development of 3 of the chicks.

Both birds are youngish Collared Sparrowhawk, possibly from different broods. The best character to pick the two species apart IF you can get a look at the feet, is the extra long middle toe of the sparrowhawk. Another feature, possibly not that reliable in recently fledged young, where the tail feathers may still be growing, or moulting adults, is that sparrowhawks have a squarish to slightly forked tail whereas goshawks are generally round in shape. there are also facial characters that also come in to play. Perhaps Geoffrey Dabb has some good head shots to show the difference.

There were (at least) 3 hawks around the upper tracks at ANBG this morning, and I got snaps of two different birds. I would be grateful if any member could identify them - whether Sparrowhawks or Goshawks (or one of each) - from the pictures below ... and if so, indicate what were the definitive features determining such decision.
