Here’s a nest that was under construction in Marcy’s cherry tree more than a week ago. By now it has eggs.
Can you tell whose nest this is? Here are some hints:
- The female selects the site and builds the nest.
- She uses grasses, weed stalks, and strips of cloth or string.
- The materials are held together with wet, soft mud that she carries to the nest to cement it. Mud is essential.
- Working from the inside of the cup, the female molds the nest to the contours of her body.
- As a finishing touch, she lines the inside with soft grasses.
- She does not maintain the nest so it deteriorates with use and might even blow out of the tree.
- It takes 5 to 7 days for her to construct the first nest of the season, a little less time for subsequent nests.
- The female builds a new nest — or builds on top of the old nest — for subsequent broods.
Whose nest is this? Leave a comment with your answer.
