Tonight, started with an owl in the exact spot as last night.  This never seems to happen, so we were all surprised.  We got to see two owls in the roost tree and got to see some stretching.  The robins gave the owls something of a break tonight.

They flyout was quick, with two owls going down to ground level quickly.  Once stayed close by for about 20 minutes giving me great looks from close up.  It then made its way south.  A few calls were made.  We’re beginning to wonder if the kids aren’t close to splitting up.

Tonight started slow.  It took a great deal of effort to find one sleeping owl.  The robins weren’t much help tonight.

After fly out, one went south along the creek and was mobbed by a few robins.  It was easy to spot and gave us some great looks.  While this was going on, two owls sang from the roost tree.

Later in the evening, two owls were spotted to the north, but we didn’t get any really good looks and certainly no photographs.

Annus Horribilis

As this year’s Manhattan Red-tailed Hawk nesting season comes to an end, it must be said this seems to be the worst year for Red-tails in the borough in recent memory.  It really was an "Annus Horribilis".

Here’s the current status of Manhattan’s known nesting pairs:

  • Houston Street – This nest ended up being "too urban", with each fledgling being picked up by animal control or the police. 

    The father was recently picked up as well after being found grounded.  He died this weekend from frounce, a disease picked up from eating infected pigeons.

    The first to be picked up has been returned to Astoria Park, and is in the "foster care" of the Triborough Bridge parents.  The parents have accepted the fledgling, but there is now a chance the bird has frounce.  It is being monitored by two dedicated Astoria hawk watchers, Jules and Peter. (Update: 7-4-08, the Houston fledgling does have frounce, which was detected on 7-2-08.  It took until 7-4-08 to find and capture the bird.)

    The two other fledglings are still with the rehabilitator Bobby Horvath and are being treated for frounce.  Their prognosis is good, but frounce can be a killer even with treatment.  (Update: 7-2-08, Sad news, one of these two fledgling has died from frounce.)

  • 888 Seventh Avenue – There was no sign of nesting this year.
  • Fifth Avenue – Despite repairs to their nest cradle, Pale Male and Lola did not produce any offspring this year.
  • 81st and Riverside – Three eyasses died due to secondary poisoning from eating poisoned rodents.  Necropsy results have not been finalized, but all three eyasses tested positive for two types of anti-coagulant rodenticide, brodifacoum and bromodiolone.
  • Cathedral Church of St. John the Divine –  The original adult male died earlier this year and was replaced with a new younger male.  There were two fledglings, one of which developed lead poisoning and has a lame foot, and is in rehab.
  • Shepard Hall, City College – There was no sign of nesting this year.  Red-tails sometimes build multiple nests, choosing one at the last minute.  However, despite repeated efforts to follow the parents, alternative sites were not discovered.
  • Highbridge Park –  Two eyasses died at about two weeks of age, reasons unknown.
  • Inwood Hill Park – Two or three eyasses depending on reporters. Two fledglings seen in the park.

So, it’s been a horrible year.  We’ve had two adults die, and numerous eyasses and fledglings be poisoned, injured or infected. 

Fort Tryon

I hadn’t been to Fort Tryon this season, so I thought it would be worth a look.  I ended up getting drenched in a thunderstorm, but I did see one Red-tailed Hawk on a building bordering the park at 196th and Broadway.  It was a second year hawk, with its tail feathers in molt.  It had a few old stripped brown tail feathers and a few new red ones.

Broadway Bridge Peregrine Falcon Family

The Broadway Bridge Peregrine Falcon family can be difficult to watch, since the bridge has two towers.  This makes it difficult to see everyone at once and figure out how many there are.

Luckily, after a rainstorm early Saturday evening all five could easily be counted and identified.  While I was there one of the parents feed one of the youngsters.  The parents don’t bring the fledglings their food, but instead make them chase them and make them catch the food in mid-flight.  It’s amazing to watch.  (The 1 train prevented me from taking photographs of the feeding unfortunately.)
