I'm guessing it is the same the world over, but here in the southern Australian bush we have a host of small, dark, quick moving birds that often make identifying and photographing in the low light- dense foliage conditions, something of a challenge at times.

We call them JBJ's or 'Little Brown Jobs'.

Sometimes to help identify a species it will be where it is, what it is doing or the call it makes. For example, Striated Thornbills are generally in the tree tops but the Brown Thornbill is seldom above 3 or 4 metres. Treecreepers work up a tree and Sittellas work down.

Now, if I can just get a Weebill to sit still long enough!
