What is the difference between Kermadec storm petrels?
Similar species: the most distinctive field mark on Kermadec storm petrels, is the contrasting white rump, which the other ‘grey-backed’ storm petrels do not share. The white breast and front, and the bounding flight pattern further distinguish it from all other storm petrels except the white-faced storm petrel.
What is the scientific name of the black petrel?
The black petrel was formally described in 1862 by the English zoologist George Robert Gray in a list of birds from New Zealand. He coined the binomial name Procellaria parkinsoni. The genus name is from the Latin procella meaning “storm” or “gale”.
Why do birds pause during the upstroke?
Similar pauses or glides during the upstroke can be observed in many birds in a range of flight modes (J. M. V. Rayner & K. D. Scholey, unpublished observations), and probably contribute to dynamic control of the flight path as well as to energy economy.
What is the scientific name of the Cape pigeon?
D. capense capense south east of Tasmania The Cape petrel (Daption capense), also called the Cape pigeon, pintado petrel, or Cape fulmar, is a common seabird of the Southern Ocean from the family Procellariidae. It is the only member of the genus Daption, and is allied to the fulmarine petrels, and the giant petrels.
What is the genus name of the Cape petrel?
The Cape petrel is now the only species placed in the genus Daption that was introduced in 1826 by English naturalist James Francis Stephens. The genus name Daption is an anagram of the Portuguese name “Pintado” which was given to the species by navigators because of its piebald plumage.
What is the scientific name of black-winged petrel?

Meat and fish were highly important ingredients in Roman cookery. Animals were also commonly employed in warfare in the Roman period. The extraordinary slaughter of animals in the Roman arena for entertainment and by organised hunting inevitably hung heavily over my study.
Do birds with rounded wings use tip-reversal upstroke postures?
For example, galliform birds with rounded wings use a tip-reversal upstroke during take-off ( Brown, 1963; Tobalske and Dial, 2000 ), and birds with rounded wings such as the black-billed magpie Pica hudsonica will alter upstroke postures according to acceleration and deceleration ( Tobalske and Dial,1996 ).
What are the most beautiful pigeons and doves in South Africa?
This species, in my mind, is the most beautiful of all the pigeons and doves in SA, and lucky for birders, is quite common in the proper habitat. The Speckled Pigeon is one of the most common birds in urban areas of South Africa and is a nice change from the boring and dirty-looking Rock Dove.

The Speckled Pigeon is one of the most common birds in urban areas of South Africa and is a nice change from the boring and dirty-looking Rock Dove.

What pets did the Romans keep?
Caged birds were popular pets There is a considerable amount of evidence for the keeping of animals as pets in the Roman world and the most commonly attested pets in the Roman world were caged birds, particularly favoured by Roman women. The popularity of caged birds is clearly demonstrated in Latin love poetry.

The popularity of caged birds is clearly demonstrated in Latin love poetry. In total, it has been estimated that in Roman poetry there are over 700 individual references to birds both wild and tame, most to wild species.

What was the role of cats in ancient Rome?
The role of cats, fish and birds. Strangely, although the Egyptians had revered cats as god-like creatures and cats in Italy today are a favourite pet, there is no evidence amongst writings about ancient Roman animals that cats were a particularly prized animal. If kept at all it is likely their value was in helping prevent the spread of rodents.

How does wing shape affect span ratio in birds?
Regardless of wing shape, the span ratio (mid-upstroke span divided by mid-downstroke span) generally decreases as a function of flight speed in birds, although it may increase with increasing speed in some passerines ( Tobalske and Dial,1996; Tobalske et al.,1999; Rosén et al.,2004; Tobalske et al.,2007 ).
How does natural selection shape bird wing design?
As a consequence of high power demands, most studies of bird flight assume that the internal and external wing design in flying birds has been, and continues to be, shaped by natural selection for efficiency in flight, with efficiency defined as mechanical power output from the muscles divided by metabolic power input to the muscles.
What are the different types of African birds?
From tiny, brightly coloured sunbirds and feisty little bee-eaters, to sinister marabou storks, prehistoric shoebills and even penguins, African birds come in an almost infinite number of sizes, shapes and colours.
