Post-hatching development of the remote-tactile bill-tip organ in precocial shorebirds (Scolopacidae). [PDF]

J Anat
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution. [PDF]

Adv Sci (Weinh)
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Dietary diversity of multiple shorebird species in an Asian subtropical wetland unveiled by DNA metabarcoding

Environmental DNA, 2022
Global declines in shorebird populations resulting from foraging habitat loss have been recently reported, and the situation within the East Asian‐Australasian Flyway (EAAF) is particularly concerning.

Eggs in the freezer: energetic consequences of nest site and nest design in Arctic breeding shorebirds [PDF]

, 2012
Birds construct nests for several reasons. For species that breed in the Arctic, the insulative properties of nests are very important. Incubation is costly there and due to an increasing surface to volume ratio, more so in smaller species. Small species

Waterbird community changes in the Wilderness Lakes, South Africa (Part 2 of 3): Shorebirds

Koedoe: African Protected Area Conservation and Science, 2023
Globally, many shorebirds, particularly the smaller migratory waders are declining, which can be attributed to multiple factors throughout their ranges.

High daily energy expenditure of incubating shorebirds on High Arctic tundra: a circumpolar study [PDF]

, 2003
1. Given the allometric scaling of thermoregulatory capacity in birds, and the cold and exposed Arctic environment, it was predicted that Arctic-breeding shorebirds should incur high costs during incubation.

Investigating avian influenza infection hotspots in old-world shorebirds. [PDF]

PLoS ONE, 2012
Heterogeneity in the transmission rates of pathogens across hosts or environments may produce disease hotspots, which are defined as specific sites, times or species associations in which the infection rate is consistently elevated.

Mechanisms promoting higher growth rate in arctic than in temperate shorebirds [PDF]

, 2003
We compared prefledging growth, energy expenditure, and time budgets in the arctic-breeding red knot (Calidris canutus) to those in temperate shorebirds, to investigate how arctic chicks achieve a high growth rate despite energetic difficulties ...

Long-Term Population Trends and Diversity Shifts among Shorebirds: A Predictor of Biodiversity Loss along the Arabian Gulf Coasts

Diversity, 2023
Bahrain is a cluster of islands in the mid-section of the Arabian Gulf that serves as an important wintering and stop-over ground for many migratory shorebirds in the Central Asian Flyway (CAF).

Probing of heavy metals in the feathers of shorebirds of Central Asian Flyway wintering grounds

Scientific Reports, 2020
The study is intended to deliver the incidence of heavy metals in the feathers of shorebirds from two important Central Asian Flyway (CAF) migratory shorebirds wintering sites such as the Point Calimere Wildlife Sanctuary (PWLS) and Pichavaram Mangrove ...
