Martins have been plentiful here and in full nest building mode. looks like I have about 20 or more birds. Was planning to do nest check this weekend and hoping for real early eggs. Up at 6:00 am this morning and turned on gourd camera. As usual, male was out and female inside. Turned back on around 8:00 am when daughter woke up and saw a object in front of camera moving slowly. Ran outside and saw birds outside of house preening and singing normal chatter. I lowered the house and coaxed the snake out and sent him back to Hell. Found dead female inside. Her head was matted down and my thought was that he tried to eat her???? No idea if they had any eggs......
I cleaned out the gourd with water and towels and replaced all the nesting material. Is that good enough? My understanding was that if Martins saw or sensed snake, they would abandon the entire house. They returned to house when I raised it and appear normal. The male returned too and keeps looking in gourd hole, but won't go in.
I have netting bunched up on bottom of poles and was going to re-install my PMCA guards this weekend also. Thought I was good till egg laying began. I feel bad.

He was a pretty small rat snake and imagine he was able to slip through the netting. I have two different sizes combined in the bunch.
On a happier note, did find first egg in the other house.
I have pics of everything and will try to attach.
Thanks for all the help this Board does.
