Pale Male and Octavia, The Search for Rose of Fordham Continues, Rare Cooperative RTH Behavior!

 The ever industrious Pale Male is still twigging for the 927 Fifth Avenue nest.
 
 Photo courtesy of http://www.palemale.com/  Octavia has developed the sleepy eyed hormonal look of a sitting formel.

 Hawkwatcher Al Olsen reports that Octavia had to wait almost three minutes beside the nest bowl after a break for Pale Male to give up sitting the eggs and make his exit.  Though I, and no one else I know, have ever observed Pale Male feed his eyasses, one gets the idea he thinks that prodigious hunting is a better use of his time, he has always displayed a grand fondness for sitting on the eggs.

No one so far has reported that Octavia has had to give him a poke with her beak to get him out of the nest bowl, on occasion, Lola, a mate of many years, periodically did oust him off the eggs that way.


June 2007, Hawkeye and Rose of Fordham 

Rose of Fordham has still not been sighted by any of her watchers and things are beginning to look grim,.

   I did receive some fascinating behavioral information from a birdwatcher at the NYBG.  Rose was observed hunting with her son called the Alpha Son or Jr.  They also double teamed the Great Horned Owls at their nest site.    I know of only two instances in which two Red-tailed Hawks participated in team hunting and both of them were bonded pairs.  Making cooperative endeavors by a mother and son even more rare.

  Mama and Papa in the Bronx were observed hunting pigeons in tandem by Jeff Kollbrunner and I observed cooperative hunting in the County M rural pair.

From  NYBG Birdwatcher-

On two occasions I saw Rose and Jr (as we called him) harassing the Great Horned Owls. It was unique behavior as he would land on a branch and the male owl ( defending the nesting female) would go into defense mode - shouldering his wings and hissing. Then Rose would suddenly appear on a branch in back of male owl- cornering him. I have never observed RT act this way before.  

Since then I've observed Rose and Jr flying and perched together. I ID her by band, color pattern and size. Last year I saw them hunting in the same manor, one distracts the prey - while the other goes in for the kill. 

I haven't seen Jr in quite sometime either. [Last observed by NYBG Birdwatcher about four months ago. DB] He was very brazen and people tolerant often buzzing the tops of our heads as he flew by. 

I watched Junior on the Museum bldg nest.  He was very aggressive in the nest and first to fledge.  I am certain it was this young male that hunted with Rose. 

Rose's favorite place to perch was the Native Plant Garden. The Garden has done extensive construction. Maybe this drove her away.   

There is another garden volunteer that photographs RT all the time. I will contact her and see if she has captured  any pictures of Rose, lately. 
Fingers crossed.

Octavia Sits the Nest. The Plaza Pair Copulate. Plus Four Winged Birds.


A heads up from Sally of Kentucky, concerning two pictures, featured on palemale.com  

 Pale Male and Octavia in similar flight positions.
This is Pale Male.  And the quick field mark for that identification if you are watching the Fifth Avenue nest?  Pale Male has a distinct sub-terminal band on his tail.
 
And Octavia's sub-terminal tail band is nearly nonexistent.

Plus yet another fascinating tidbit from Robin of Illinois-Early birds had four wings?


"More than 100 million years ago, birds living in what is now China sported wings on their legs, a new study of fossils suggests.  Researchers found evidence of large leg feathers in 11 bird specimens from China's Shandong Tianyu Museum of Nature. The feathers suggest that early birds had four wings, which may have played a role in the evolution of flight, scientists report in a study published today (March 14) in the journal Science."
And a Clarifying Update on the Downtown Plaza Pair from Budding NYC Hawkwatcher Al Olsen in Case You Were Still Confused-
Talked to two hawk watchers who  thought that Mr. Plaza didn't have a mate. I told them about Stella and Katherine's observations when they saw O [Octavia, D.B.] and Pale Male uptown copulating and the Plaza pair copulating down south at nearly current time.  Seems someone is telling  them that isn't true.  It is. I was in park that day.
  I have been trying to track the southern hawks for  days now, more or less successfully. Have seen both hawks and copulation. 
Yesterday, I located the male on the Essex sign.   He flew west just as another hawk (his mate) flew off Crown building.  Crown hawk landed in big London Plane tree in the edge of Park by the wall and leaned forward in "the position". It was Plaza female. I'd lost Mr. Plaza but after five minutes or so he flew in and copulated with Mrs. Plaza.  They sat together for about six minutes and she flew back in direction of Crown. 
It can't be Octavia because she is sitting on the nest at Fifth Avenue and is said to have laid an egg or eggs besides the reliable observations of Stella, Katherine, and others.

Many thanks for the clarifying observations Al, and keep those updates coming! 
Happy Hawking!
