Provision of artificial shelter on beaches is associated with improved shorebird fledging success

, 2011
Artificial chick shelters might improve productivity of beach-nesting birds threatened by anthropogenic disturbance. We investigated the efficacy of three different chick shelter designs against four criteria: accessibility to chicks over time, thermal ...

Snowy Plover reproductive success in beach and river habitats

Journal of Field Ornithology, 2005
Poor reproductive success has contributed to the decline and low population size of the federally listed Western Snowy Plover (Charadrius alexandrinus nivosus), especially where it breeds on coastal beaches used by humans for recreation. From 2001-2004, we compared reproductive success of color-marked plovers breeding on ocean beaches with those on ...

A novel hybrid beachgrass is invading U.S. Pacific Northwest dunes with potential ecosystem consequences

Ecosphere
Invasive plants formed via hybridization, especially those that modify the structure and function of their ecosystems, are of particular concern given the potential for hybrid vigor. In the U.S. Pacific Northwest, two invasive, dune‐building beachgrasses,

2022 Final Report on the Western Snowy Plover

, 2023
In 2022, we monitored the Western Snowy Plover (WSP) population at Coal Oil Point Reserve as in previous years. The number of breeding adults was 52, higher than the average of 37 for our site. The wintering population size was 183, also above the average of 167. Skunk predation was the primary cause of nest failure.

Fall Field Report, August–November 2015 [PDF]

, 2015
To start, a housekeeping item: in the species accounts that follow, whenever I use the term migrant I am referring to fall migration only. Many species, of course, have differing migration strategies and timing in spring and fall. Much of the data used
