Puffinus baroli
(Bonaparte, 1857)

The Barolo shearwater (Puffinus baroli), also known as the North Atlantic little shearwater or Macaronesian shearwater, is a small shearwater which breeds in the Azores and Canaries of Macaronesia in the North Atlantic Ocean. The English name and the specific baroli refers to Carlo Tencredi Falletti, marquis of Barolo.

Taxonomy

Barolo shearwater was formally described in 1857 by the French naturalist Charles Lucien Bonaparte under the binomial name Procellaria baroli. [1] The specific epithet commemorates Carlo Tencredi Falletti, marquis of Barolo. [2] This shearwater is now placed in the genus Puffinus that was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the Manx shearwater (Puffinus puffinus) as the type species. [3] [4] The species in monotypic: no subspecies are recognised. [4]

It was previously considered conspecific with the little shearwater (Puffinus assimilis) of the southern hemisphere. Mitochondrial DNA cytochrome b sequence analysis indicated that baroli and boydi were very close to the nominate subspecies of Audubon's shearwater. [5] BirdLife International retain the forms baroli and boydi within little shearwater. The British Ornithologists' Union accepted P. baroli as a distinct species in 2005, [6] as has Clements Checklist . The American Ornithologists' Union followed in 2013. [7]

Description

Features that distinguish the Barolo shearwater from the Manx shearwater and other North Atlantic Puffinus species include the pale face, silvery panel in the upperwings, shorter more rounded wings, and blue feet. [8] As well as the pale face with the darkly contrasting eye. [9]

Distribution

The Barolo shearwater breeds on the Azores, Desertas, Savage and Canary islands. [10] The largest colony, of 1400 pairs, occurs on the Selvagen Islands. [11] The non-breeding range is the tropical and sub-tropic northeast Atlantic. [12]

Behaviour

The Barolo shearwater feeds in the upper 15m of the water column, which is similar to the closely related Audubon's shearwater Puffinus lherminieri of the western Atlantic and Caribbean Sea. Barolo shearwaters do not have a preferred time of day to forage or rest and they may hunt for food during either day or night, although they seem to be more ready to fly in the daylight hours. They feed mainly on fish and cephalopods, with Argonauta argo being the most common cephalopod taken in the Azores but also being part of a diverse selection of cephalopod prey, while the fish taken were almost exclusively Phycis spp. [13]

Threats

Like other Procellariforms, introduced predators (rats and cats) must be their main threats at breeding colonies. In addition, fledglings are attracted to artificial lights at night during their maiden flights from nests to the sea. [14] On Tenerife, Canary Islands, a decline on the number of birds attracted to lights have been reported, suggesting a population decline on the island. [15]

Shearwaters are medium-sized long-winged seabirds in the petrel family Procellariidae. They have a global marine distribution, but are most common in temperate and cold waters, and are pelagic outside the breeding season.

<span class="mw-page-title-main">Procellariidae</span> Family of seabirds which includes petrels, shearweters and prions

The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters. This family is part of the bird order Procellariiformes, which also includes the albatrosses and the storm petrels.

<span class="mw-page-title-main">Manx shearwater</span> Species of bird

The Manx shearwater is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman word for the cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits.

<span class="mw-page-title-main">Balearic shearwater</span> Species of bird

The Balearic shearwater is a medium-sized shearwater in the seabird family Procellariidae. Puffinus is a Neo-Latin loanword based on the English "puffin" and its variants, that referred to the cured carcass of the fat nestling of the Manx shearwater, a former delicacy. The specific mauretanicus refers to Mauretania, an old name for an area of North Africa roughly corresponding to Morocco and Algeria. The Balearic Shearwater is listed critically endangered by the IUCN and is one of Europe’s most endangered seabirds.

The sooty shearwater, or tītī, or muttonbird, is a medium-large shearwater in the seabird family Procellariidae. In New Zealand, it is also known by its Māori name tītī, and as muttonbird, like its relatives the wedge-tailed shearwater and the Australian short-tailed shearwater.

<span class="mw-page-title-main">Zino's petrel</span> Small seabird in the gadfly petrel genus

Zino's petrel or the freira, is a species of small seabird in the gadfly petrel genus, endemic to the island of Madeira. This long-winged petrel has a grey back and wings, with a dark "W" marking across the wings, and a grey upper tail. The undersides of the wings are blackish apart from a triangle of white at the front edge near the body, and the belly is white with grey flanks. It is very similar in appearance to the slightly larger Fea's petrel, and separating these two Macaronesian species at sea is very challenging. It was formerly considered to be a subspecies of the soft-plumaged petrel, P. mollis, but they are not closely related, and Zino's was raised to the status of a species because of differences in morphology, calls, breeding behaviour and mitochondrial DNA. It is one of Europe's most endangered seabirds, with breeding areas restricted to a few ledges high in the central mountains of Madeira.

<i>Calonectris</i> Genus of birds

Calonectris is a genus of seabirds. The genus name comes from Ancient Greek kalos, "good" and nectris, "swimmer".

<i>Bulweria</i> Genus of birds

Bulweria is a genus of seabirds in the family Procellariidae named after English naturalist James Bulwer. The genus has two extant species, Bulwer's petrel and Jouanin's petrel. A third species, the Olson's petrel, became extinct in the early 16th century; it is known only from skeletal remains. Bulwer's petrel ranges in the Atlantic, Indian and Pacific Oceans, whereas Joaunin's petrel is confined to the northwestern Indian Ocean. Olson's petrel is known from the Atlantic.

<span class="mw-page-title-main">Pink-footed shearwater</span> Species of bird

The pink-footed shearwater is a species of seabird. The bird is 48 cm (19 in) in length, with a 109 cm (43 in) wingspan. It is polymorphic, having both darker- and lighter-phase populations. Together with the equally light-billed flesh-footed shearwater, it forms the Hemipuffinus group, a superspecies that may or may not have an Atlantic relative in the great shearwater. These are large shearwaters which are among those that could be separated in the genus Ardenna.

<i>Pseudobulweria</i> Genus of birds

Pseudobulweria is a genus of seabirds in the family Procellariidae. They have long been retained with the gadfly petrel genus Pterodroma despite morphological differences. Mitochondrial DNA cytochrome b sequence analysis has confirmed the split out of Pterodroma and places the genus closer to shearwaters. They thus represent either a plesiomorphic lineage still sharing some traits of the ancestral Procellariidae with the gadfly petrels, or convergent evolution of a shearwater to the ecological niche of gadfly petrels.
