Great Frigatebird (Fregata minor) Melbourne June 2016.
My first ever frigatebird, and a very impressive creature. Huge but narrow wingspan, and massive gular sac.
There are currently two of these birds in Port Philip Bay, Melbourne, and I saw this one after work today over Frankston. Very far outside its normal tropical distribution, presumably blown down by the big storm this week.
Poor photo quality, due to low light and high wind! :D
