Loon (Gavia immer) Science Article 4 abstract A 2-yr study was conducted on the winter behavior of the Common Loon (Gavia immer) at Weekapaug, Rhode Island. Behavior of loons was assessed by recording the type of activity every 60 s for a 5-min period. Activity budgets showed an increase in the amount of time spent […]

Loon (Gavia immer) Science Article 3 abstract Many wild Common Loons have been exposed to mercury contamination; thisstudy will help increase understanding of how it affects their lives by providinginformation about digestive efficiency. The assimilated mass coefficient (AMC) foreight captive-reared Common Loons (Gavia immer) was determined by this studyto be 80% of dry fish. Rainbow […]

Loon (Gavia immer) Science Article 1 abstract Breeding Common Loons (Guvia immer) are well known for vigorously defending their territory from conspecifics. Territory holders are not previously known to be supplanted by loons during the breeding season. I observed a pair of adult Common Loons displace a resident pair from their territory shortly after a […]

Loon (Gavia immer) Science Article 2 abstract The proposed project uses genetic markers from nuclear and mitochondrial genomes to assess genetic structure, migration patterns and population dynamics in common loons (Gaviaimmer). Observations of loons on breeding grounds indicate that 1) mated pairs are highly philopatric, 2) effects of environmental contamination and habitat degradation can impair […]
