I don't know about Catbird dispersal but I would suggest 20 km is not a lot
for dispersal. Also in general, if you hear sounds of just one species and a
range of these, it is not usually likely to be mimicry, it is more likely to
be the real thing, unless there is some reason why not. Most mimics copy a
range of sounds, and usually in subsong, so not very loud. So the calls they
reproduce are generally not one species, but a range of species sounds.
There are some specialist mimics, such as Lyrebird & Regent Honeyeater that
do very specific behaviour. As for what other bird/s might reproduce a range
of Catbird vocalisations? The question is not about the Catbird, The
question would be what species known as mimics do you have in your area,
that may also visit forest. All sorts, Satin Bowerbird is an obvious option,
O-b Oriole, Magpie....... I once had a Wedge-tailed Eagle (and other things)
calling from the tree in my yard. It wasn't, it was an Oriole.

>From the garden a few days ago, I could have sworn I heard a Catbird. At
about 20km from Catbird rainforest, I wonder:
- whether Catbirds disperse/ migrate in midsummer? or
- what other bird/s might reproduce a range of Catbird vocalisations?
