Title: Northern Sparrowhawk ??
Post by anonymous_guy on Jul 1^st, 2005, 6:27pm

Best I could do considering the light, foliage & my small lens
Was chasing a much smaller bird through the tree canopy (didn't catch it !!)

In structure, it has a bigger head and shorter body and tail in proportion. This is a small accipiter that rules out either Northern Sparrowhawk or Crested Goshawk.

Breast has thick brown patch and belly has thick bars. So, this is a Besra. Japanese Sparrowhawk is very similar but paler colour on breast and thinner bars on belly. Also, the Japanese Sparrowhawk is less likely to occur in Hong Kong in July but during the autumn passage time (i.e. October and November).
