Greetings,
Among (many) other things, for Singing Bushlark HANZAB says '...rather
large,rounded head, with slightly elongated feathers of crown forming, at
most, very short, blunt crest when raised (invisible when folded);...'
Regards, Clive.

Hi All,
On the weekend I photographed a few Singing Bushlarks (Australian Larks)
with thier crests raised.
4 Images of 3 different birds can be seen here:

The field guides I have say that a Singing Bushlark is distinguished from
a Skylark by the lack of crest.
Can anyone with HANZAB confirm whether a crest is listed as a feature of
Singing Bushlarks? Is it only a feature for certain subspecies?
Also, does anyone know whether crests are known to act as a "heat sinks"
for birds to regulate head temperature?
Regards,
Peter
P.s. Photos taken near Geelong in Southern Victoria of two isolated
groups. The temperature was heading towards an expected 40 degree day, but
it was only about 30 degrees at the time.
