This is a South Texas birdhouse with 12 rooms. It may have tiny mexican fruit bats living inside of it which can eat 11x their body weight in mosquitoes in one night! I say go ahead bats and pig out! 
 
MSG Roy P. Benavidez,
HQ, B-56 (Project Sigma), Fifth Special Forces Group. Born 5 August 1935 on a small farm near Cuero Texas. Entered service June 3, 1955, at Houston TX.
Voluntarily accompanied evacuation force from his forward headquarters on 2 May 1968 and rescued several isolated patrol members in heavy combat near Loc Ninh, five kilometers inside Cambodia.
12 members of his unit were pinned down by a North Vietnamese Regiment and were in a desperate situation. In the foreward to Benavidez's book "Medal of Honor, One Man's Journey from Poverty and Prejudice" H. Ross Perot describes what he did this way, "Sergeant Benavidez and a small band of heroes came to the rescue. Despite numerous wounds- he was shot five times, riddled with shrapnel, and bayoneted and clubbed during hand-to-hand combat- Ray returned again and again to lead the wounded survivors to the rescue chopper and retrieve the bodies of his dead comrades. In a final act of patriotism, he pushed his bullet-ridden body back to the ambushed soldiers' highly classified documents and electronic gear and destroyed them to keep them out of enemy hands. Only then did he allow himself to be pulled into the helicopter."
He is now buried in Fort Sam Houston National Cemetary.
