FW: [canberrabirds] Whiskered Tern at Kelly's this am - again

Dear Sicheng Wan

 

Yes, they do indeed.  Martin Butterfield of this chatline has recently drawn attention to breeding near Canberra (see below).  On the other hand the closely related White-winged Black Tern visits Australia as a non-breeding migrant.

Do they breed in Australia? From the photography they seem to have breedi; plumage.

Cheers

Yes  -  the Australian headquarters of the species is probably Werribee, where seasonally there are tens of thousands, easily the most common bird in the area.  They have a particular liking for hover-hunting over roadside strips of feral rape, which must be very rich in insect life.  The birds plunge completely into this.  In the below the distinctive profile of the You Yangs can be seen in the background.

The words of HANZAB are interesting.  Based on observations from the Northern Territory there is apparently a marked difference between sexes with males eating more fish and females more invertebrates.  

 

During last year's breeding event on the Hoskinstown Plain the Terns were frequently seen flying in flocks over grasshopper ridden paddocks 100+ metres from the waters edge.  Given the ephemeral nature of that marsh, and it not having a direct connection with a permanent water body I doubt greatly if there were any fish in it.
