This is the time of year in which we receive many telephone calls about small birds that have collided into people's windows. They are often confused with being a baby bird, but we can rule that out at this point, as "baby season" is over.
Often with window collisions, there is no visible injury: the bird is stunned and can often recover quickly. Other times, it can take longer. You may notice the bird appears puffed up or hunched over; in other cases, it looks like the bird has a broken neck (head is cocked upside down). It is actually not a broken neck, but a head injury where the symptoms are known as torticollisis, or "stargazing"(see photo below of Red-tailed Hawk). In any case, the bird can be gently placed into a cardboard box (such as a shoebox) with one or two small holes poked in the box for ventilation. Put the box in a dark, quiet place such a garage or a bathroom and allow it some time to recover. If after an hour or two the bird is still incapacitated, contact us or another rehabilitator for further assistance. Do not try to feed the bird, or give it water: a dark, quiet place, and some time are all it needs at this point.
Why does this happen? There are several reasons:
Vision: While it is fairly easy for most birds to avoid building and large objects, they can have difficulty perceiving transparent obstacles, such as windows and other panes of glass. Furthermore, when plants are displayed inside on a windowsill, this makes it look as if a safe flyway exists.
Migration (which is happening now): Adult birds, often mistaken as baby birds, are often found colliding into windows each fall. These birds are birds that have migrated back to our area. Tired after travelling perhaps a thousand miles, they are often confused by windows and/or lighted buildings. New York City is a major flyway for migrating birds, and in an attempt to reduce collisions at this time of year, NYC has instituted a "Lights Out" program to reduce the number of collisions.
Territory: While this situation usually happens in the spring, it is still worth mentioning.
Sometimes birds intentionally crash into windows (and side view mirrors of cars, glass doors, etc); this is usually territorial. There is either a nest nearby or the bird is seeing its reflection and defending its territory. Try to put something up to block his reflection, and they usually move onto something else.
What can you do to help? There are several steps you can take:
-Have bird feeders either far back in the yard, or within a few feet of the window. This leaves less room for the birds to fly; window strikes will occur at a slower speed and the bird is less likely to be hurt.
-Avoid placing plants on your windowsill, as this can be confusing to birds.
-Reduce window reflections by having screens or shades covering the window. Blinds are also helpful, as they can be moved to reduce reflections while still allowing you to see outside.
-Purchase items that help prevent window collisions:
*Collidescape: A thin transparent film that attached to the window. Visit this website for a demonstration on how it works.
*Droll Yankees “Warning Web”: static cling that attaches to the window:
* I have also found a economical and fun way to reduce reflections by using seasonal
gel clings such as these: http://www.impactinnovationsinc.com/gel-clings.html
on windows. They can usually be found in pharmacies such as CVS and Rite-Aid.
Below are a few photos of birds that have come into our hospital after colliding with windows:
Top photo: This is a Red-tailed Hawk that collided through a picture window, shattering the window and breaking off half of her beak (visible in the photo). Unfortunately, after 4 months and after much discussion with other raptor experts, due to damage done to the bony core of her beak, structurally her beak would not grow back and we had to make the difficult decision to put her to sleep.
Below: Palm Warbler that collided into a window. This bird was released.
This is an example of "stargazing" - see how this bird is holding his head cocked sideways?

This is a very young Red-tailed Hawk that came into our facility after suffering head trauma. His recovery took a long time, and at a crucial age developmentally, he became very accustomed to people, growing up around them. He is one of our permanent Education Animals (Baby) and can be seen any day in our outside aviary, where he lives with his female friend, Lucky Lady.
Join us to welcome spring and learn all about young wild animals. We will have crafts for kids, games, live animals and more! Admission is free. "Baby shower gifts" from the following list are greatly appreciated.
Lastly,on Sunday at 1pm, we'll be participating in our first Nature Adventure at the Arboretum! Come on down to meet our Virginia Opossums and Eastern Grey Squirrels and learn about the wonderful adaptations of our local mammals! Following our program, a nature hike with Bailey Arboretum's naturalist will take place at 2 pm. We hope to see you there!
Now, the weather appears to have done a total 180! The snow has all melted and we are enjoying 50 degree temperatures and sunny skies! With the nice weather this week so far, our permanent resident animals have had lots of enrichment time outside of their enclosures. Below is Wyatt, our resident Eastern Grey Squirrel, on a morning romp in the yard:
Also enjoying some time outside her enclosure was Millie, our Virginia Opossum. Millie is pictured here sitting atop our brand new fence.
Here's another picture of the fence. It fits in so well with the feel of our new home!
