The high counts were of flocks of 60 birds ca. 60 km off Men - docino, CA 16 May 2012 and 90 birds 47 km off Curry, OR 8 May 2014. MARBLED GODWIT (Limosa fedoa) A single bird was off Monterey, CA 27 Sep 2011 and a flock of 22 birds was 58 km off Mendocino, CA 18 Jul 2013. The status of this species offshore is not well known, although the localized southwestern Alaska popula - tion—L. f. beringiae—is known to make non- stop flights across the northeastern North Pa - cific (Gratto-Trevor 2000). RED KNOT (Calidris canutus) Migrant flocks well offshore included 9 birds ca. 75 km off Curry, OR 8 May 2009, 19 birds 79 km off Humboldt, CA 3 May 2013, and 30 birds 66 km off Mendocino, CA 7 May 2015. In fall, 1 was off Monterey, CA 30 Sep 2008. LEAST SANDPIPER (Calidris minutilla) Beyond 55 km from shore, 1 bird was ca. 140 km west of southern Haida Gwaii 30 Aug 2013, and a flock of 11 was 100 km off Clatsop, OR 4 May 2016. This species' status offshore is not well known. SPOTTED SANDPIPER (Actitis macularius) One was 55 km off Curry, OR 21 May 2015. Presumably, this species is rare well offshore. GREATER YELLOWLEGS (Tringa melanoleuca) One was off Lincoln, OR 17 Sep 2007. This species' status offshore is not well known. LESSER YELLOWLEGS (Tringa flavipes) One was 75 km south of the southern end Haida Gwaii 4 Sep 2013. This species' status offshore is not well known. RED-NECKED PHALAROPE (Phalaropus lobatus) This is typically the dominant phalarope spe - cies in inshore waters, where cruise ships GREAT EGRET (Ardea alba) One was 59 km west-southwest of Point Sur, Monterey, CA 3 May 2016. GREEN HERON (Butorides virescens) One was 69 km off Curry, OR 14 May 2012. WHITE-FACED IBIS (Plegadis chihi) One bird was off southern Washington, where rare, 10 May 2013. Three birds were near Santa Barbara Island, CA 28 Sep 2011. Shorebirds –––––––––––––––––––––––––––––––––––––– A few individuals and small flocks of the fol- lowing species are known to be regular mi- grants over the offshore northeastern North Pacific Ocean. They were seen during spring and/or early fall during cruises as far offshore as the shelf edge, approximately 55-90 km offshore: Semipalmated Plover (Charadrius semipalmatus; 1 seen ca. 245 km off Curry, OR 29 Aug 2013), Ruddy Turnstone (Arenaria in - terpres), Black Turnstone (A. melanocephala), Sanderling (Calidris alba), Dunlin (C. alpina; 1 seen ca. 190 km off southern Oregon 29 Aug 2013), Western Sandpiper (C. mauri), Long- billed Dowitcher (Limnodromus scolopaceus), dowitcher sp., and Wandering Tattler (Tringa incana). Accounts for 11 species accompanied by additional information follow. BLACK-BELLIED PLOVER (Pluvialis squatarola) Individuals and flocks of spring migrants may be seen well offshore, with 2 separate individuals 80 and 87 km off Humboldt and Del Norte, CA, respectively, 3 May 2013, a flock of 4 birds 56 km off Coos, OR 30 Apr 2014, and a flock of 30 birds 60 km west- northwest of the northern end of Vancouver Island (presumably heading toward Haida Gwaii or southeastern Alaska) 18 May 2016 the farthest offshore at this season. A southbound migrant was 105 km off Humboldt 1 Aug 2015. GOLDEN-PLOVER SP. (Pluvialis dominica/fulva) Generally a rare or very rare migrant in much of California, an American/Pacific Golden- Plover was off Monterey 18 Sep 2007. WHIMBREL (Numenius phaeopus) Uncommon but regular spring migrant out to (46.57° N, 125.24° W) 15 Sep 2015; 58 km west of Bandon, Coos, OR (43.21° N, 125.14° W) 21 Sep 2015; 52 km northwest of Cape Blanco, Curry, OR (43.05° N, 125.13° W) 21 Sep 2015; 30 km off Point Piedras Blancas, San Luis Obispo, CA 29 Sep 2015; and 64 km west of Cabrillo Point, Mendocino, CA (39.29° N, 124.56° W) 1 Dec 2015. BRANDT'S CORMORANT (Phalacrocorax penicillatus) Common to abundant north to southern Brit - ish Columbia within 20 km of shore; rare farther offshore. Most remain within ca. 25 km of mainland or island roosting and nest - ing sites (Briggs et al. 1987). The species is very rare in southeastern Alaska between late spring and early fall: 1 was off the mouth of Chatham Strait (55.87° N, 134.47° W) 6 Aug 2015. Singles seen up to 77 km and 58 km off San Luis Obispo, CA 11 Nov 2015 and 21 Sep 2016, respectively, were very far from land. PELAGIC CORMORANT (Phalacrocorax pelagicus) Not typically a pelagic species, with most in - dividuals found within 10 km of shore, with a few out to 20 km (Briggs et al. 1987). Pe - lagic Cormorants were seen regularly in small numbers (up to 7/day) from cruise ships as far as 115 km offshore transiting (presum - ably) between Vancouver Island and Haida Gwaii; one was 147 km south-southeast of the southern end of Haida Gwaii 26 May 2014. Elsewhere, a few birds have been seen up to 30 km off southern British Columbia and Washington, 1 was 76 km southwest of Point Piedras Blancas, San Luis Obispo, CA 8 May 2013, and another was 45 km off Point Conception, Santa Barbara, CA 29 Sep 2015. BROWN PELICAN (Pelecanus occidentalis) None seen during cruises beyond inshore wa - ters during spring and summer. Briggs et al. (1987) noted that most birds are found with - in 20 km of shore, with a few out as far as 88 km or 3000-m depth, and that Brown Peli - cans typically do not remain at sea overnight, but rather they return to roost sites on shore. In fall, seen as far as 30 km off Pacific, WA 1 Oct 2012, ca. 70 km off Lane and Coos, OR 29 Sep 2008, and 66 km off Point Arguello and 55 km beyond San Miguel Island, Santa Barbara, CA 26 Oct 2012.
