STERCORARIIDAE (6 species)
This family is often merged with Laridae.
Catharacta antarctica Brown Skua
NOTE: Mitochondrial cytochrome b studies (see Olsen and Larsson 1997) indicate that n and s hemisphere Catharacta separated prior to differentiation of the latter into the 3 generally-recognized taxa, hamiltoni, antarctica, and lonnbergi. Thus it seems justified to consider n and s hemisphere populations specifically distinct; timing of breeding and molt would indicate continuing divergence between n and s hemisphere populations. It has been suggested that hamiltoni and antarctica be treated as subspecies of a species distinct from lonnbergi; the distinctive population of the Kerguelen Is (currently included in lonnbergi) may also be a discernible taxon (see Olsen and Larsson 1997).
C. a. lonnbergi Breeds NZ pop fewer than 2000 inds (SI 3 prs, Solander Is 2+ prs, Stewart I 20 prs), Chatham Is 260 inds (breeds throughout except Chatham, Aikman and Miskelly 2004), Snares Is 300+ inds (Miskelly et al 2001), Antipodes Is 50-100 prs (Tennyson et al 2002), Auckland Is 100 prs, Campbell I 100 prs, Macquarie I 550 prs.

Cas c Pacific Hawaiian Is (May-Nov, Pyle and Pyle 2009; one banded 24 February 2006 as a chick in Admiralty Bay, King George Island in the South Shetlands (62 10'S), by Wayne Trivelpiece ... "This bird has not yet been resighted at the breeding colony, which means it is still on its usual 3-5 year trip around the Pacific Ocean basin. SP skuas that fledge from our area go north after fledging and it seems whichever side of the tip of S. America they encounter, they follow the coast of Chile or Argentina northwards until they eventually reach the Arctic (AK or Greenland) 2-4 years later. We normally see young birds back at our study site between their 4th- 6th years. This is our first resight from HI and an important one as I had only ever had sightings from Coastal areas prior to this, not from such an isolated, mid-ocean island as HI."- post to HAWAIIBIRDING by Robin Baird); Marshall Is (listed as C. skua, Great Skua, but likely this sp., Spennemann and Benjamin 2004), Kiribati (Line Is, Phoenix Is), Dec Tonga, Samoa, Jan Fiji.

S. pomarinus Pomarine Jaeger
NOTE: Relationships and genetic history of this species are unresolved; see summary of hypotheses in Christidis and Boles (2008). OSNZ (2010) places this species in its own genus Coprotheres as it appears intermediate between Catharacta and Stercorarius.

From Declan Troy (2004): "Transmittered 4 birds Barrow, Alaska (71°N) . All the birds
remained near their nest sites into September then exploded away from
Barrow. The birds dispersed widely to the extent that during much of the
fall there was an individual in each quartisphere of the globe (all in the
Pacific Ocean). The migration of one individual is illustrated. This bird
quickly crossed into the eastern hemisphere and remained in Russian waters
until reaching Japan. It loitered around eastern Japan until mid-November
then proceeded rather directly south though the Solomon Islands to
Australia. This individual made a U-turn around 35°S (south of Sydney) and
back-tracked north off the Australian coast. The reversal in direction was thought to be a local movement rather than
the start of spring migration but this will remain unknown as contact with
this individual was lost in February 2007." Cas Galapagos Is (Swash and Still 2005), Nov-Dec Chatham Is (Miskelly et al 2006). Acc Lord Howe I (Feb 2010, Morris). Cocos I (Montoya 2008b). Hypo Caroline Is (Truk, Pyle and Engbring 1985).

A. imitator Imitator Sparrowhawk
Res Solomon Is (Choiseul, Santa Isabel, Bougainville, Hadden 2004a, Dutson 2011)
May be more numerous on Isabel than prev thought, as field separation from A. albogularis is difficult; dark specs of Accipiter from Isabel have been previously assigned to A. albogularis, but all dark and pied specs in AMNH are in fact A. imitator and no specimens of albogularis are known from Isabel (Kratter et al 2001, LeCroy et al 2001).
F: Solomon Is (Bougainville: only 4 recs, Hadden 2004a; Santa Isabel: Garanga R uncommon, Kratter et al 2001; very rare, Wheatley 1998; 2 thought albogularis, but specs indicate all on Isabel are imitator, Hornbuckle 1999; Choiseul: very rare, Wheatley 1998).
A. gularis Japanese Sparrowhawk
Sometimes considered conspecific with A. virgatus Besra Sparrowhawk. Reichel and Glass (1991) noted Jouanin's conclusion that the Oct 1877 Guam specimen in the Paris Museum matched neither A. virgatus nor A. gularis, but that the measurements made by Jouanin suggested either A. virgatus or A. nisus Eurasian Sparrowhawk. Ferguson-Lees and Christie (2001) consider reports of sparrowhawks from Izu, Ogasawara, and Iwo Is, as well as Palau, likely gularis.
