Many of our favorite songbirds breed, live, and migrate to/from the Boreal Forest, only passing through Iowa seasonally. When their breeding habitat is destroyed, the population dwindles and the chance of viewing the likes of a Yellow bellied Flycatcher in our backyard diminishes.
For this portion of the project, birds were selected that migrate through Iowa seasonally, are not year round residence of Iowa, and have over 70% of their breeding ground in the North American boreal forest ring — 37 birds in all.
