Ardeidae - hybrids in Texas (1 Viewer)

Hi All,

There are a few known instances of hybridization between heron species so if one keeps looking those hybrids are probably one’s best chance to find one. In the past 10 years I have seen three of them in Texas; found two and one was reported in an area I visit several times a year, so it was easy to run into it.

It is hard if not impossible to identify parents without DNA studies, but one can always speculate and makes presumptions. Perhaps some people are interested in this subject and will share their thoughts and ideas.

1) Night-Heron hybrid seen for a few weeks on Texas Central Coast Mustang Island last year – quite interesting bird.

2) Egret hybrid – Upper Texas Coast Bolivar area; perhaps a few extra words about it

Here to see the size comparison - much larger and taller (even with much shorter, deformed neck) than Reddish Egret so about body size of Great Blue Heron; photos were taken from the same distance but these two birds were too far apart from each other to have them fit in one frame (both photos are not cropped)

Closeup of the deformed neck with skin and spine visible; anybody has an idea if this is a birth defect (perhaps a result of hybridization) or there is a possible another explanation.

Hope some will have fun trying to figure out who mated with who.

Cheers,

Very interesting indeed, thanks for posting.
I'd suggest the parentage of #1 is likely Black-crowned Night Heron x Green Heron.
