My first visit to the rookery at the UT Southwestern Medical School campus in Dallas, TX was a month or so ago. I met fellow blogger, Jason of xenogere, for a personal tour. My second visit was a couple of weeks ago, and I took a friend along to see the wonders of this magical place first-hand. We walked around the small park, overflowing with egrets, herons, and other birds – without my camera. (I make a much better conversationalist when I don’t have a camera at the ready.) I walked around the park a second time, after offering my friend the air-conditioned comfort of my car. I struck out on my own with my camera and tripod across my shoulder.
This Black-crowned Night-Heron (Nycticorax nycticorax) stole the show, IMO. The place was alive with the ephemeral glow of hundreds of Great Egrets (Ardea alba), but it was the secretive, lurking night-herons who captured my rapt attention.
I drew red arrows on the picture above to point out the fancy plumes that signal the night-heron is an adult. As far as I can tell, the males and females look alike, so it can be difficult to know whether we have a male or a female here.
The Black-crowned Night-Heron is named, in part, because of the black feathers on its crown (top of the head), as shown here. The other part of their name is due to the fact that they feed mostly at dusk, night, and dawn. The scientific name means “night raven.”1 Cooooool…I like that!
The males perform a courtship dance, described as follows:
“After selecting a nesting site, the male erects his breast feathers and back plumes, stretches his neck upward and forward, and bows. As he does this he treads from one foot to the other. At the lowest point in his bow he utters a hissing sound”2
I watched this heron raise and lower each foot in succession for about a minute. He did not display the other characteristics of the courtship dance, so I doubt this picture captures a moment within such an activity. Still, it is fun to imagine it, isn’t it?
If you’ve been keeping up with Birder’s Lounge, then you know that I am quite fond of featuring pages from very old bird guides. Here is the page for the Black-crowned Night-Heron from the Red Book of Birds of America:3
Another interesting tidbit I picked up about this bird is the fascinating-but-gross defensive maneuvers they sometimes employ. “They are aggressive and defend themselves by regurgitating and defecating on intruders.”4 Nice! Can you imagine the scene if this night-heron that I was photographing decided that I was an intruder rather than a paparazzi?
Show’s over folks…move along. Besides, I had a friend waiting patiently in the car. 😉
I’ll post pics of the Great Egrets in the coming weeks.
Before I close, I would like to mention that I have been asked by Dawn (dishwashing liquid) to contribute posts to their Everyday Wildlife Champions page on Facebook. I am the first in what will be a series of featured nature/wildlife bloggers to serve as panelists in the new Wildlife Advocates section. I am supremely honored by the invitation!
Dawn has a 30-year history of wildlife rescue and has recently launched the Everyday Wildlife Champions movement for everyday people to get involved and help. As a part of this movement, Dawn is launching Wildlife Advocates to feature bloggers and highlight the great work they have been doing. To learn more about the Wildlife Advocates, check out www.facebook.com/dawnsaveswildlife
I have been on, and then off, and now on-again with Facebook. I will remain on Facebook to facilitate my role as a blogger/panelist for Dawn’s Wildlife Advocates. So, here is my badge:
My first post on Dawn’s Everyday Wildlife Champions page is up! The next one will be posted on Friday, April 30th.
