Red or Green and what Specie

Could somebody reference an actual study done to determine which color in a dark barn is least likely to alarm roosting birds? Also wonder if, say pigeons respond differently than do starlings, or collared doves.

Then there's personal experience. Maybe more valid than official research.

My experience with Starlings roosting in a dark barn at night was that when the red beam was in flood/wide angle mode the birds were nervous but didn't move. How ever it was also not quite enough to allow a confident sight picture through the scope. When the red beam was tightened down and the light intensity was enough that one could get a confident sight picture the birds flew if the light was on them for more than a couple of seconds.

I do have an ATN X sight the first version. It's like trying to shoot upward with a bowling ball duct taped to the receiver. The infrared light on the left side of the scope just insures you always shoot with a cant. Can't and don't want to afford one of the later generation night scopes that are much clearer and lighter. My scope lit with a red or green beam ensuring I could see well enough to score the kill would be much better.

All things the same would the reaction of the birds be different with green?


 
I had the same problem at the farm. I placed red LED lights inside the barn loft with them shining up at the rafters. Left them on 24/7 for 2 weeks. When I resumed shooting the birds, the red light on my rifle didn't spook them. I learned this from a raccoon problem I had 2 years ago. They became accustomed to the motion detector turning on a security light after a very short time and paid no mind. I increased the brightness until I could see them well enough to eradicate them.
