Darter query

Australian Ravens

Rosemary,

at this time of year many (all??) A. Ravens roost communally.  Pre and post roosting they may appear at places in larger numbers and there they may be very vocal, chase each other etc, and hence become very noticeable. Some of my recent examples include in mid February 19 ravens early morning on Lyneham Ridge, at least as 'noisy' as a group of Pied Currawongs; in early and mid March 30 (one morning) and 37 (one late afternoon) around Norgrove Park/Kingston Harbour, spending most of their time on house roofs and especially in the scaffolding and a tall crane at the building sites there.

Have to date not found an actual roosting site, they tend to fly in very late to their final destination.

Yesterday at 14.00hrs there was a Darter busily diving upstream of the stepping stones on Sullivans' Creek, ANU.
A delightful encounter to the east of ANU's Sports complex. Is it usual to be seeing the species within the ANU campus?

Are the territory's suburbs usually inundated with Ravens at this time of the year?
Around Flynn, the ANBG (on Saturday) and elsewhere they are making more noise than Currawongs prior to rain &/o air-pressure changes.
