Birds here on the Cape and Islands are very busy: courtship and nesting, and more spring migrants arriving. On this month's Bird News on The Point, we hear the latest reports on sightings, and all about nests and nest boxes. Also a conversation about the use of chemical pesticides in our yards. Mark Faherty, ornithologist and wildlife biologist at the Wellfleet Bay Wildlife Sanctuary, joins host Mindy Todd in the studio. Listeners from around the region join in with comments and questions.
