It's been a cold winter here in the Blue Mountains. My birdbath froze solid and for a couple of weeks last month it barely thawed out - even by the end of the day it still resembled a little ice-skating rink! You could almost see the confusion on the faces of the younger currawongs when their beaks touched the ice as they tried to drink. The older currawongs had it worked out. They got their water from the small shallow birdbath meant for scrubwrens and thornbills, which happens to be in a more sheltered part of the garden and didn't freeze as often. The past 2-3 weeks have been balmy by comparison and the frosts less frequent now.

No matter how cold it is, one of the very best things about winter here is the lyrebird song. June being the height of lyrebird season, during that month I made a few morning trips up to Mt Victoria where there are some particularly virtuoso birds. In a gully near Pulpit Rock is a male who mimics at least 22 different bird calls, including all the usual lyrebird favourites like Eastern Whipbird, Crimson Rosella, Gang-gang, Pied Currawong and Golden Whistler, as well as things like the Brown Thornbill, White-eared and Yellow-faced Honeyeaters, a juvenile currawong being fed, and the hawk-alarm call of New Holland Honeyeaters. I also heard it mimic a couple of calls that I haven't heard any other lyrebird do: Rockwarbler and Red-browed Treecreeper. Several times it mimicked two whipbirds calling in unison - something that I've heard whipbirds do occasionally with only the slightest difference in timing to reveal that it's two birds instead of one. I was also quite amused to hear when this lyrebird mimicked Yellow-tailed Black-Cockatoo, it was answered by a distant, real YTBC.

Although the female lyrebirds will still be engaged in nesting duties, the males' display has all but petered out now. At the same time the Satin Bowerbirds are renovating their bowers and gearing up for spring.

Cheers,
