General

Herald Petrel: Medium-sized petrel that has three color morphs: light, intermediate and dark. Dark morph bird is dark gray overall with dark forehead and cap and thin black bill; shows silver-gray to white base on underwing flight feathers. Light morph has white breast and belly and dark gray upperparts. Intermediate forms exist between light and dark morphs. Sexes are similar.

Range and Habitat

Herald Petrel: These birds prefer water below the Equator but were recorded as far north as North Carolina where it is a rare but regular visitor in late spring to late summer. It is known to breed on Raine Island and possibly other small cays in the Coral Sea, and forage in surrounding waters. This bird is mostly pelagic and spends its life at sea coming to nesting grounds only to breed. For breeding it chooses warm islands with soils suitable for nesting burrows.

Breeding and Nesting

Herald Petrel: One white egg is laid in a burrow which is excavated or cleaned out by both sexes. For their breeding grounds Herald petrels choose warm islands and do not line burrows with any nest materials. Incubation ranges from 49 to 54 days and is carried out by both parents.

Foraging and Feeding

Herald Petrel: This bird is mostly pelagic and spends the majority of its time at sea where it feeds on squid and crustaceans. When looking for food, it skims water, grabs prey with bill, and ingests while in flight.

Vocalization

Herald petrel: Generally quiet when flying over water, but during breeding times when they fly over the colonies on land, they make a rapidly repeated high-pitched "ki ki ki ki" call. It also makes several squeaky whistles and moaning notes and can produce cooing and chattering tern-like sounds.

Similar Species

Herald Petrel: Sooty Shearwater has light underwings, shorter tail, broader, more stout body, high forehead and a very different flight pattern. Murphy's Petrel has white at the base of its bill.

Flight Pattern

Fluttery wing beats alternate with glides., High erratic soaring arcs become higher and more dashing as wind speeds increase.

Upperparts

Back, rump, hindneck, wings, and crown.

Belly

The ventral part of the bird, or the area between the flanks on each side and the crissum and breast. Flight muscles are located between the belly and the breast.

Breast

The upper front part of a bird.

Cap

The area on top of the head of the bird.

Flight feathers

Located on the wing, and collectively called remiges (singular, remex). The long stiff feathers are subdivided into two major groups based on the location and are called primaries and secondaries.

Pelagic

The pelagic is a type of bird whose habitat is on the open ocean rather than in a coastal region or on inland bodies of water (lakes, rivers). An example of a pelagic bird is the blacklegged kittiwake.

4 and 6 letter alpha codes

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.
