Rain or Shine . . .


You might remember our June 23 Facebook post of Jamaica, one of our red-tailed hawk ambassadors.  We featured a photo of her standing half-in/half-out of the sunlight in her new education housing.

It was quite rainy in the Twin Cities this morning.  As you can see from photos, Jamaica and Strix the barred owl chose to get their feathers wet!  Whisper the barn owl, however, chose the cover of her hutch under which to continue dozing.

Answer to Skull Post

Thank you to all who took some guesses at the raptor skull featured yesterday. It is a Northern saw-whet owl skull. What may have helped many of you are the asymmetrical ear openings (shown with arrows in photo here), and the bony structures in the skull called sclerotic rings.

Whose Skull Is This?


This skull is from a raptor species.  Can you guess which one?  And why do you think so?

We'll post the answer tomorrow!  Good luck!

Eastern Screech-owlets Get Some Help



Two orphan owlets.  You can see that one
is a gray phase (left) and one is red!  In front
of them is a recently cast pellet. 

Home is where the heart is.  We have all heard this term before, but for four orphaned Eastern screech-owlets, the heart of their early existence was broken.  Their home area (nest cavity and surrounding trees) was completely logged for development in late May.  With no parents to raise them and teach them survival skills, they quickly came to TRC’s clinic for a helping hand.  We were able to foster two with another local Eastern screech-owl family, but are still looking for a couple of other owl families to place the remaining youngsters with.  

This is the hutch that we are recycling
as a temporary home "nest cavity" for the
owlets.



Eastern screech-owlets are cavity nesters, and it is often challenging to find nest locations.  Most often, they are discovered when the young fledge, hang out around the nest cavity, and vocalize near dusk, requesting a meal.  If you know of an Eastern screech-owl family in the Minneapolis/St Paul area, please let us know by calling 612-624-4745 or emailing arent@umn.edu. These youngsters will have the best chance of survival if they can be taught by experienced adult Eastern screech-owls.  We have had great success fostering orphans with the same species, but they must be close in age to the youngsters already present.    

In the meantime, the owlets are living in one of TRC’s new outdoor rehabilitation pens, and recently fledged from the cavity they were provided.   The little “hutch” was used formerly by our education department for one of our winged ambassadors, so we are recycling it for clinic use. The owlets will begin “mouse school” soon if not fostered (in which the owlets are presented with opportunities to hone their hunting skills with live prey in a controlled setting), and will have to stay with TRC for a while as they improve their hunting and flying skills.  Their temporary home may be at TRC, but their hearts will forever remain wild.

Peregrine Chicks Banded at 33 S. 6th Street in Minneapolis



 Four peregrine chicks – two males and two females - were banded at a site in downtown Minneapolis, which has had the names of Multifoods Center, City Center, and currently 33 S. 6th Street.   This site is historically very important to the Midwest peregrine falcon restoration project.  It was the first urban site to host a “hack box” of peregrine chicks, and the first Minnesota site since the 1960s to produce a wild-hatched peregrine that would fledge successfully.


In 1985, Dr. Harrison “Bud” Tordoff and Dr. Patrick T. Redig, co-founder of The Raptor Center, approached the building management team at 33 South 6th Street to inquire about putting a “hack box" (also known as a "release box") on the roof. This release box would house young captive-bred peregrine chicks that would be the start of a reintroduction of the species.

TRC staff provide leadership, technical advice, and administrative support for the Midwest Peregrine Society, which includes 13 Midwest states and two Canadian provinces.



Here is a video of peregrine chicks being banded, taken by the AHC, at a previous year's banding at this site.  

The history of the Midwest peregrine restoration project, as well as a searchable database for the public to look up individual birds, sites and states, is here.
