Bathtub Bird



Early Monday morning we got the call. A woman in Los Lunas had a bird in her bathtub (No water). Could Hawks Aloft come get it? The first thing to establish: was it a hawk?

We have a series of questions we ask to determine, as closely as possible, what type of winged creature a member of the public has. This person was adamant she had a small hawk, probably a Kestrel. Transporting and handling a raptor usually takes special skills. Before driving an hour to pick up a bird, we ensure it is one of our target species; raptor, corvid, or roadrunner, because anyone can transport a songbird to the Wildlife Rehabilitator.

The next question: was it truly injured? Many fledgling birds, including raptors, are "kidnapped" from the wild each year because well-meaning people pick them up when they are in the awkward "just out of the nest" stage. They will be clumsy fliers for a few days, but their parents continue to care for them. Even trying to watch the bird to determine if it is abandoned will keep the parents away. Right now, it is mostly passed fledgling season. So the little bird was probably not a "brancher" learning to fly. The Los Lunas folks were able to easily scoop up this particular bird with a towel, and the husband proceeded to examine its wings and legs without the bird retaliating (i.e. grabbing him back!). So this bird was probably injured.

Our Raptor Biologist, Ron Kellermueller, found on his arrival that the bird in the bathtub was indeed a hawk - a Sharp-shinned Hawk, smaller relative of the Cooper's Hawk so ubiquitous to the Rio Grande bosque. When he arrived at the office with his feathered charge, we did a quick once over and found no broken bones, but a marked discrepancy in the fleshiness on either side of the keel. Just like our muscles atrophy without use, if a bird has an injury that prevents proper flying, the muscles of the keel will wither from disuse. The one-sided nature of this bird's muscle problem pointed to a possible fracture of the coracoid, a collar-bone like part of a bird's skeletal system. This bone provides muscle attachment for the strong flight muscles of the chest. A fractured coracoid will prevent flight. The good news is, with cage rest and supportive care, this little bird should make a full recovery, and be back to terrorizing songbirds soon!
