My response is that whilst Geoffrey's response is rather facetious, that is also understandable. I am left wondering what sort of help you want, Jude. As in you are the one that was there, I, like the rest of the readers were not, so I don't know what we can add. You list things that suggest a Brown Falcon, and reasonably suggest that is what you think it is. There is no reason why it wouldn't be. Given that, I would be happy to leave it as that. (As for example the young Brush Cuckoo that Con posted the other day.) I don't know what would raise with you a green impression, nor what you mean by "shorter rounded wing shape". As in more short and round than what? Likely by comparison with other species that have long, pointed wing shape, though that is a guess. A Brown Falcon has a longer more pointed wing shape than a Brown Goshawk (one of the confusable species). But a Brown Goshawk does not have very clearly marked 'teardrops', so it wasn't that.
 
A minor point that you wrote markings as a juvenile Brown Falcon but the variation in this species is so wide and with no easily seen age features, that it is my belief that deciding on what is a juvenile, rather than an adult, from appearances alone, is something that can only be done in the best circumstances of observation and / or by someone who knows them really well. As in other than by behaviour, such as an adult feeding a chick, there is no way a person would pick it as a juvenile and yet not be certain of what species it is.

Dear Chatliners,

 

Yesterday, Currawang, -34.980854,149.510965, markings as a juvenile Brown Falcon with very clearly marked 'teardrops', back extremely dark greenish brown, belly brown with white vent, shorter rounded wing shape, no feathering on legs. Size consistent with BF.

 

Ta.
