I have the contact info for the Brunswick bridge project managers and will be sending/forwarding them the info about the nesting Cliff Swallows and will post any communication i receive.  

Since there are a few DNR Osprey members, i wanted to ask them what are the chances that the bridge work schedule can accomodate these birds and even if it is mandatory that the work accomodate these birds?  Does the migratory bird treaty (see below) come into play?

Migratory Bird Treaty Act of 1918
From Wikipedia, the free encyclopedia
Under United States Code Title 16, Chapter 7, Subchapter II, the Migratory Bird Treaty Act of 1918 is the United States legislation implementing the convention between the U.S. and Great Britain (for Canada). It replaced the Weeks-McLean Act, which had become effective in 1913. The United States subsequently entered into similar agreements with four other nations (Canada, Mexico, Japan and Russia) to protect migratory birds. The statute makes it unlawful to pursue, hunt, take, capture, kill or sell birds listed therein ("migratory birds"). The statute does not discriminate between live or dead birds and also grants full protection to any bird parts including feathers, eggs and nests. Over 800 species are currently on the list.

Partial Listing of Covered Species
The following is a sampling of some of the more commonly known birds of the over 800 species covered under the treaty:
Bald Eagle, Haliaeetus leucocephalus
Black-capped Chickadee, Parus atricapillus
American Black Vulture, Coragyps atratus
Northern Cardinal, Cardinalis cardinalis
Cedar Waxwing, Bombycilla cedrorum
Cliff Swallow, Hirundo pyrrhonota (stopped the list here)
