While checking on the Memory Lake Colony in Grantsburg, WI today, I noticed a female stuck in one of the entrances. At this time of the season martins fight, sometimes very seriously, for compartments. During the early spring, martins have been reported stuck in many different types of entrances. This poor bird ended up stuck in the entrance hole with another female martin on the inside. Thankfully, I was able to free this bird and the bird stuck in the compartment. The bird trapped in the compartment pecked at the back of this martin, causing some minor damage (missing feathers, red skin). Hopefully she will make it. The female stuck in the compartment was freed unharmed. This incident demonstrates the importance of carefully monitoring your colony.
