México is federally protected; however, unlike in the US, habitat in México receives little or no active<br />
management. Nevertheless, large conservation gains have been made in México with the eradication <strong>of</strong><br />
predators from 6 <strong>of</strong> 13 known breeding isl<strong>and</strong>s <strong>and</strong> 3 <strong>of</strong> 4 historical/likely breeding isl<strong>and</strong>s <strong>and</strong> the removal <strong>of</strong><br />
herbivores from 6 known breeding locations <strong>and</strong> 2 historical/likely breeding isl<strong>and</strong>s. Despite these gains,<br />
ongoing threats <strong>of</strong> non-native mammal introductions to murrelet isl<strong>and</strong>s <strong>and</strong> threats from disturbance <strong>and</strong> habitat<br />
destruction are greater in México than the US. The building <strong>of</strong> a liquid natural gas terminal at Los Coronado<br />
Isl<strong>and</strong>s, the world’s largest breeding colony <strong>of</strong> S. h. scrippsi, may cause the ongoing loss <strong>of</strong> large numbers <strong>of</strong><br />
murrelets, due mostly to light pollution <strong>and</strong> disturbance. NGOs, primarily Conservación de Islas, play a key<br />
role in managing murrelet habitat in México; by promoting federal Biosphere Reserve status for all Xantus’s<br />
Murrelet breeding isl<strong>and</strong>s, they will help establish long-term protection for this species.<br />

The Common Loon, Gavia immer, breeds throughout the northeastern United States. Several surveys<br />
have assessed the abundance <strong>and</strong> distribution <strong>of</strong> summering loons. However, timing, migration patterns, <strong>and</strong><br />
wintering range have not been adequately documented. During the summer <strong>of</strong> 2003, four Common Loons (three<br />
adults <strong>and</strong> one juvenile) from NY, NH, <strong>and</strong> ME were implanted with satellite transmitters. The transmitters<br />
were manufactured utilizing three different duty cycles corresponding to breeding, migration, <strong>and</strong> wintering<br />
periods. Data were received for each transmitter within 24 hours <strong>of</strong> data acquisition. From late August 2003 to<br />
mid-March 2004, we obtained 787 high-quality locations (Argos Location Class 1–3), accurate to
