Title Mercury in tree swallows and feathers of other species that line tree swallow nests at

Acadia National Park, Maine

Project Description Objectives: Objectives of the project were (1) to expand the breadth of an ongoing study by Dr.

Haines (Sources, Fate, and Effects of Mercury in Aquatic Systems at Acadia National Park,

Maine, and Cape Cod National Seashore, Massachusetts) to include an insectivorous bird

species, (b) to characterize the extent of mercury contamination and transfer from lower trophic

levels (i.e., aquatic insects) to the insectivorous tree swallow, and (c) to evaluate the potential of

using feathers of other species that are collected by tree swallows to insulate their nests to

characterize mercury contamination in the surrounding avian community. After the second year of

study it was possible to add an additional year (1999) of data collection by keeping the Acadia NP

study site as a control site for comparison to a Superfund site in MA being evaluated in a

companion study. By doing this, we were able to collect an adequate sample from an additional

pond (Aunt Betty Pond)on Acadia NP.
