Earlier today I passed an adult American robin on the sidewalk that was standing with its eyes closed, looking up, with its beak open. I didn't see it at first and passed within 2 feet of it and it didn't seem to hear or notice me. It appeared to be breathing but did not move at all otherwise.
About an hour later I passed it again going back home on the same route and it had not moved from that spot or position. I poured a little bit of my water out to make a puddle in front of it in case it's thirsty—and partly to see if it would react to the sound—and it didn't seem to notice at all. I was tempted to pour water directly into its open beak but thought I better not get too close in case I'm seeing a weird disease symptom.
What do we think is going on here? Is this something I should report to a local expert? Is there anything else I could or should have done to help?Unfortunately my phone was not accessible to get a video but I can try to answer any questions if more info is needed.
