Nest‐site selection by cinnamon teal and other ground‐nesting ducks in Great Salt Lake wetlands
Wildlife Society Bulletin, 2023 Ground‐nesting ducks can reduce nest depredation by selecting nest sites where local physical structures or vegetation provide olfactory or visual concealment.

Age dependent reproductive effort in great tits
Journal of Avian Biology, Volume 2026, Issue 1, January 2026.Senescence, the decline in reproductive value with age, is well documented in natural systems, but the underlying mechanisms remain an enigma. A decline in parental effort with age potentially explains reproductive senescence, but age effects on parental effort have been little investigated.

Ashtabula Breakwater Common Tern (Sterna Hirundo) Nesting [PDF]
, 2016 Purpose: This document summarizes the design features used to create a nesting area for the Common Tern (Sterna hirundo) that was incorporated as part of the maintenance repairs to the harbor breakwater located in Ashtabula, OH. The purpose of the tern nesting project was to demonstrate an option that can be used during such maintenance activities for ...

Evolutionary Applications, Volume 19, Issue 1, January 2026.ABSTRACT Many migratory species have experienced severe population declines, but the genetic consequences of such declines are still rarely assessed. The last Central European population of gull‐billed terns (Gelochelidon nilotica) has declined from 500 breeding pairs in the 1940s to 52 in 2025, whereas Mediterranean populations of this migratory ...

Revista de Biología Tropical, 2001 We studied how waterbirds used two small estuaries during the non-breeding season of 1995-1996. These estuaries, El Chorro and Majahuas, were located in the middle of a large span of non-wetland habitat along the Pacific coast of México.

Premature feather loss among common tern chicks in Ontario: the return of an enigmatic developmental anomaly [PDF]
PeerJ, 2016 In July 2014, we observed premature feather loss (PFL) among non-sibling, common tern Sterna hirundo chicks between two and four weeks of age at Gull Island in northern Lake Ontario, Canada.

Ibis, Volume 168, Issue 1, Page 79-94, January 2026.Many seabird species are in decline and population demographic models are important for revealing the causes and developing conservation strategies. Natal and breeding dispersal are key parameters of such models but can be challenging to estimate and may vary by sex.

Nest-site habitat partitioning by Arctic, Common, and Roseate terns
Avian Conservation and EcologyWhen closely related species that share aspects of their habitat niches nest in sympatry, selection is expected to favor species-specific differences in nest-site selection that allow birds to partition habitat. We tested habitat-partitioning theory in a
