Phosphate Enrichment From Wildlife Inputs Shapes the Distribution and Pigmentation of Green and Red Snow Algae Along the West Antarctic Peninsula

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Snow algae darken snow through biomass accumulation and pigmentation, yet nutrient controls on algal abundance and pigment composition in Antarctic snowfields remain poorly constrained. Along the West Antarctic Peninsula (WAP), coastal snowfields receive nutrient inputs from marine and wildlife sources that may influence bloom development.

Measuring the Recreational Use Value of Migratory Shorebirds on the Delaware Bay [PDF]

In this article we estimate the recreational use value of household trips to view shorebirds during the annual horseshoe crab/shorebird migration on the Delaware Bay. We use contingent valuation to estimate the value of day and overnight trips separately

Relationships between chick vocalizations and parental absence in Kentish Plovers

Ibis, Volume 168, Issue 4, Page 1437-1447, October 2026.
Chick calls within bird species vary greatly, often in relation to whether parents are present. We studied chick calls in a nidifugous shorebird, the Kentish Plover Anarhynchus alexandrinus, in three circumstances—(1) on the nest with parental presence; (2) on the nest with parental absence; and (3) out‐of‐nest with human observer presence—and ...

"The Economic Value of Viewing Migratory Shorebirds on the Delaware Bay: An Application of the Single Site Travel Cost Model Using On-Site Data" [PDF]

Using data from an on-site survey of recreational birders in southern Delaware during the annual horseshoe crab/shorebird spring migration, we estimated four truncated count data models of recreation demand accounting for endogenous stratification due to

Studies on seasonal variation in metabolic rate related to changes in body composition with particular reference to shorebirds (Charadrii) [PDF]

, 1992
The basal metabolic rate of three species of shorebird was measured throughout the non-breeding season. These measurements were related to change in body mass and body composition.

Knowledge gaps in trace element contamination of shorebirds and allies along the East Asian–Australasian Flyway: A review

Avian Research
Trace elements (metals and metalloids) are naturally occurring substances that may be essential at trace levels but become toxic pollutants at higher concentrations, accumulating in biological systems and posing severe risks to wildlife.

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

Ibis, Volume 168, Issue 4, Page 1422-1436, October 2026.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Time‐stressed Bar‐tailed Godwits exploit novel prey during migratory fuelling

Ibis, Volume 168, Issue 4, Page 1681-1695, October 2026.
Long‐distance migratory birds breeding in the Arctic face challenges as earlier snowmelt shifts the timing of vital resources. To keep up with these advancements, birds will need to modify their migration. Higher fuelling rates during stopover have been identified as a critical mechanism for accelerating migration, but this requires adequate food ...

Sea-level rise causes feeding habitat loss for migratory shorebirds in remote coastal wetlands of Brazilian Amazon

Environmental Research Letters
Sea-level rise (SLR) can cause significant changes in coastal wetlands, such as the retreat of coastlines and sedimentary shifts in tidal flats. In areas lacking coastal defenses, rising sea levels are expected to drive the inland migration of coastal ...

Population estimates and land cover use of wintering Mountain Plovers in Texas

Journal of Field Ornithology
Conservation of migratory birds throughout the full annual cycle requires a comprehensive understanding of abundance and distribution in interconnected breeding, migration, and wintering habitats.
