This paper describes an investigation into the factors influencing the occurrence and duration of the wing-spreading behaviour of the Cormorant. It was found to occur only after a period in the water (that is, when the plumage was wet), and its duration to be inversely related to wind speed and the length of time spent in the water. In addition birds tended to face into the wind during wing-spreading and, at low wind speeds, away from the sun. The extent to which the wings were spread was also…

The Water Penetration and Repellency of Feathers Revisited
Abstract. We revisit the water penetration and repellency of feathers and these factors' relation to bird behavior and habitat in the light of information that has become available since 1985. We…
Aerial shaking performance of wet Anna's hummingbirds
TLDR
The remarkable ability of hummingbirds to perform rapid shakes in order to expel water from their plumage even while in flight is reported on.
Orientation to solar radiation in black wildebeest (Connochaetes gnou)
TLDR
It is calculated that a black wildebeest adopting parallel orientation throughout the diurnal period would absorb 30% less radiant heat than the same animal adopting perpendicular orientation.
Daily variations in the thermoregulatory behaviors of naked neck broilers in an equatorial semi-arid environment
TLDR
It can be concluded that naked neck broilers adjust their behavior in response to daily variations in the thermal environment and wing-spreading and beak-opening behaviors are important adaptive responses to the thermal challenges posed by the equatorial semi-arid environment.
Chapter 2 Feather Structure and Behavioral Patterns in Seabirds
TLDR
It is concluded that the flight and contour feathers exhibit morphological and mechanical features that are advantageous for specific habitats and feeding techniques that suit their specific habitat and feeding habits.
Takeoff flight performance and plumage wettability in Cassin’s Auklet Ptychoramphus aleuticus, Xantus’s Murrelet Synthliboramphus hypoleucus and Leach’s Storm-petrel Oceanodroma leucorhoa
TLDR
Examination of takeoff performance both before and after experimentally submerging the birds indicated that wingbeat frequency, speed and mass-specific power (peak and mean), and energy per wingbeat decreased in all species when plumage was experimentally wetted, whereas mean acceleration increased.
The chewing lice (Phthiraptera: Ischnocera, Amblycera) of the great cormorant (Phalacrocorax carbo).
Modeling Flightless Galapagos Seabirds as Impacted by El Nino and Climate Change
TLDR
Results suggest the current Cormorant population is still stable, but the Penguin faces a 20% probability of extinction in 100 years if current conditions remain, and interventions such as captive breeding could be suitable for population recovery.
Effects of temperature on gular fluttering and evaporative water loss in four sympatric cormorants in southern Africa
TLDR
Findings indicate that temperature increases from climate change will likely have serious direct impacts on nesting cormorant colonies in southern Africa by as much as 25% by 2100 under current projected temperature increases and increases in water loss could reach nearly 10%.
Vestiges of the natural history of development: historical holdovers reveal the dynamic interaction between ontogeny and phylogeny
  • A. Werth
  • Biology
    Evolution: Education and Outreach
  • 2014
TLDR
Examples of developmental remnants are presented, which often involve circulatory and reproductive alterations, and numerous other retained or reappearing historical holdovers are discussed in ways that reveal the unfolding dynamic interaction between genotype and phenotype.

Spread-winged behaviour of double-crested and flightless cormorants Phalacrocorax auritus and P. harrisi: wing drying or thermoregulation?
TLDR
Spread-winged behaviour in Double-crested and Flightless Cormorants appears to function primarily in wing drying and not in gaining or losing heat, although the ultimate goal of wing drying may be to conserve metabolic energy.
Spread-wing postures and the water repellency of feathers: a test of Rijke's hypothesis
-Rijke (1967, 1968) proposed that the water repellency of feathers and the presence or absence of spread-wing postures in water birds could be explained by a structural mechanism first described for…
Energetics and Spread-Winged Behavior of Anhingas in Florida
-Metabolic rates and body temperatures of four captive Anhingas (Anhingu anhinga) were measured over a range of ambient temperatures. In addition, Anhingas were observed in the field in an attempt to…
Plumage and Ecology of Cormorants
TLDR
The paper draws on data attending the etho-ecology of four species of cormorants in support of an hypothesis for the adaptive significance of the predominantly dark plumage of these birds.
THE WATER REPELLENCY AND FEATHER STRUCTURE OF CORMORANTS, PHALACROCORACIDAE
TLDR
The results show that the dimensions and special arrangement of the barbs are different from those in ducks, which is directly responsible for a lesser extent of water repellency as encountered in cormorant feathers.
Environmental Influences on the Energetics and Behavior of Anhingas and Double-Crested Cormorants
The energetics of anhingas and double-crested cormorants were measured and their behavior monitored under an array of environmental conditions. Anhingas have lower basal metabolic rates and higher…
