Most taxa have white cheeks and ear-coverts, but these are black in albiventer, purpurascens and melanogenis. The nest may be made of seaweed and guano on a cliff or of sticks in a bush or tree. Crowned Cormorant, South Africa, by Adam Riley. But both cormorants and, in particular, darters are unique in having feathers that are less naturally water-resistant than other birds, an adaptation that enables them to forage underwater more easily. No, a cormorant is a bird and has feathers. Cormorants and darters are long-bodied and that, paired with feet at the far end of their bodies, makes them awkward when out of the water. Shags on the other hand, while being hilarious to our non-birding anglophile friends, don’t appear to be taxonomically distinct, and the term is generally used to describe only the smaller, stubbier-billed, cormorants. It is also known as the blue-eyed shag, blue-eyed cormorant and by many other names, and is one of a larger group of cormorants called blue-eyed shags. [3] Chicks are uniform brownish, and immatures are brownish and white (instead of black and white), have dull facial skin, and lack the orange-yellow nasal knob and blue eye-ring. Shags do, however, typically have a jaunty tuft of feathers on the head, or at least the original shag, Eurasian Shag, does, which differentiates it from the plainer original cormorant. While most cormorants are humbly attired in nappy black, several species, particularly in the southern hemisphere, are real stunners with varying shades of white and steely gray and colorful feet and faces. The world’s largest diamond comes from Africa. The comparatively aquatic and frequently freshwater cormorants and darters are outliers, both in habitat preferences and panache, but we’re all about the underdogs here. The one known in North America as Great Cormorant, but in Europe as the definitive article. [11] Many chicks and eggs are lost to predators such as skuas and sheathbills. So happy about the return of “I and the Bird!” Learned a lot and only snickered a little bit about “Shags.” So immature of me but there you go! Let’s take the two families together, and then separately. Great edition, Nate! Where Are You Birding This Final Weekend of October 2020. They use their spear-like beaks to impale their prey, requiring them to perform an elaborate, learned, maneuver to toss the fish from beak to throat. The imperial shag has a total length of 70–79 cm (28–31 in) and weighs 1.8–3.5 kg (4.0–7.7 lb), with males usually larger than females. Cormorants have a long hook-tipped bill, patches of bare skin on the face, and a small gular sac (throat pouch). The two to four chalky eggs, pale blue when fresh, hatch in three to five weeks, and the young mature in the third year. There’s scarcely a bird in the world as unfairly maligned, deemed the world over as a bad seed due to its ungainly proportions and reportedly insatiable appetite for bait fish. © 2019 10,000 Birds // All rights reserved. The taxonomy is very complex and species-limits within this group remain unresolved. Learn how your comment data is processed. Omissions? Others consider the all or part of the group conspecific. Though there is no good evidence that cormorants have a negative impact on gamefish, it is sadly not a species that sees many rally to its defense. Are cormorants social? Flightless Cormorant, Galapagos, by Scott Winton. In the Orient and elsewhere these glossy black underwater swimmers have been tamed for fishing. However, this necessitates regular time out of the water to dry sodden feathers and regulate body temperature; the time spent in that classic crucificial position. For the species from New Zealand, see. Phalacrocoracidae (Cormorants) in: del Hoyo, J., Elliott, A., & Sargatal, J. eds. Alternatively, some recognize two species, the white-cheeked L. atriceps (with subspecies bransfieldensis, nivalis and georgianus) and the black-cheeked L. albiventer (with subspecies melanogenis and purpurascens),[10] or it has been suggested that three species should be recognized: L. atriceps (including albiventer), L. georgianus (with subspecies bransfieldensis and nivalis), and L. melanogenis (with subspecies purpurascens and possibly verrucosus, though the latter is relatively distinctive, and most consider it a separate species, the Kerguelen shag).[3]. Sitting atop a cliff face or piece of flotsam following a fishing outing, they’ll spread their wings wide to dry. The basic philosophy behind techniques to scare birds away from a fishery is that cormorants are startled sufficiently to move to other foraging sites by means of auditory, visual or even chemical deterrents. [3], Overall this species is not considered threatened and is consequently listed as Least Concern by BirdLife International and IUCN. This book, written by a nun named Juliana Barnes, covered the topics of hunting, fishing, and coats of arms, and it also included the first-ever list of collective nouns for every type of animal one could possibly imagine.
