Cheers George!

Cool stuff - interesting little birds. I'll send you some of my records
through if you'd like a looky. Looking at my own records I've seen Brown
Gerygone almost every visit I've had to Bunyip and most of the year round,
particularly on the eastern side (this is also the only area I've seen
species like Wonga Pigeon and Pilotbird). Also just having a look at eBird,
there's a handful of records for just east of Melbourne and seem to suggest
they're around most of the year too!

Thanks for the info - interesting stuff!
