Dear all, 
 
Some colleagues and I are writing on the topic of polarized light pollution and 
its ecological impacts. We are looking for citations/references and photographs 
of birds that have mistakenly landed on asphalt parking lots. It Waterbirds 
occasionally mistake parking lots for water and this may be due to its strong 
polarization signature. I've found a few vague references to grebes, loons and 
dovekies doing this. Any photos or references would be appreciated.

Incidentally, other references to (or anecdotes about) potential ecological 
impacts related to polarized light pollution would be appreciated. For example, 
plastic bags floating in water have a polarization signature that may resemble 
that of jellyfish, ctenophores and other organisms. Given that several aquatic 
predators appear to be polarization sensitive, and that this could enhance 
their prey detection ability, polarization may explain plastic bag ingestion by 
sea turtles. I haven't yet looked to see how common ingestion of this kind of 
garbage is. 

Thanks for any help.
