I spent a little time watching an active Bullock’s Oriole nest at Fernhill Wetlands. Notice how the birds have incorporated strands from a blue plastic tarp into the nest. Using plastic debris in nest construction is not unusual. In Kansas I saw a Baltimore Oriole nest made entirely from fishing line. The plastic makes a sturdy nest, but the material can be deadly if a bird gets a foot entangled in it. These orioles, including the baby shown here, seem to be doing alright.
After feeding the kids, the male stopped to pose in all his orangey deliciousness. Summer is the time to slow down and study the local nesting species. Checklists can be pretty short this time of year, but the slower pace gives you a chance to really get to know the locals.
