From Southwest Virginia Wildlife Center of Roanoke

Meet RSHA 26-2599, the Red-shouldered Hawk! This patient lies at the center of a recently-solved MYSTERY at our wildlife hospital.

Miss RSHA 26-2599 is a mature adult hawk who was found grounded in a driveway about a mile from our facility. On arrival, we checked for the usual suspects: Broken bones, lead toxicity, eye issues, head trauma, emaciation, bruising from any kind of collision or altercation. ALL were within normal limits (except for one, but we'll get there).

The diagnosis: At over 910g in weight, she was too darn fat to fly! We couldn't even palpate her keel due to the heavy layer of fat covering it.

It is RARE for wild animals to become obese without human intervention, so how could this happen? Was she a lost falconry bird? Someone was feeding her? Was she an escaped (illegally-kept) captive hawk?

After ruling these out, we asked the finder if any of her neighbors had free-ranging chickens she could be eating.

The finder did some asking around, and called us back to confirm a couple of weeks later: YES! Her neighbors' free- roaming chickens were disappearing at an alarming rate over the last few weeks.

Our mystery was very likely solved! This queen was picking off the buffet of easy prey set out before her, eating her fill, and then snoozing in the trees nearby until she was ready to eat again. The chickens were let out in the morning, she ate another, and repeat.

After weeks of repeating this feasting and sleeping, it's no wonder she got too fat to fly!

This story is kinda funny (unless you're the chickens getting eaten), but there is a sobering reality: This is a man-made issue, and this could have had a sadder ending if she had been found by a larger predator instead of the finder. Without flight, she is extremely vulnerable.

Moral of the story: Don't feed wildlife... Directly OR indirectly. Also, covered runs are the way to go for chicken keeping!

I saw this and was wondering why the eyes were green! Green eyes like this in a bird are usually a sign of injury. Their blood turns green instead of purplish like ours when it breaks down. Turns out, this was just part of the exam.

From image comments:

We were doing an eye stain to check for any surface damage to the cornea! Basically we apply a non-toxic dye, then view the eye under uv/black light in a darkened room. If there is a scratch, abrasion, or ulcer, the deeper layers of the cornea absorb the dye and glow bright green.

    Hey OP the green blood thing really intrigued me, but I'm not finding anything online about bird blood turning green as it breaks down. Do you have any resources where I can learn more about that?

    She was living next to a bottomless bucket of fast food chicken nuggets

    Humans are only slightly better at this. Bulking up for scarcity is still a very strong instinct. But the scarcity never comes...

    That's still a pretty recent change for us as a species.

    I keep seeing articles about how our current trending global climate change is putting us at risk for widespread crop failures. I looked at the wiki for famines and they have a whole section discussing several environmental and agricultural trends that could lead to massive future problems in the near term.

    The short term success of our species can't necessarily ensure long term stability. It's probably a good thing these genetic survival skills take a very long time to change. It feels a little crazy to think life could change so significantly for the negative, but it's not beyond the realm of possibility.
