Before diving into the well-deserved Christmas Holidays, I have updated several pages. The new papers can be found below. Apart from that, I received some excellent pictures from Steve Byland (be sure to check out his website: http://www.stevebyland.com/).
Feel free to send me papers I have missed and pictures of possible hybrids.
Merry Christmas and Happy New Year!

Presumed hybrid between Little Blue Heron (Egretta caerulea) and Little Egret (E. garzetta)
