N O R T H A M E R I C A N B I R D S 380 usual away from the coast, while one even far- ther inland at Clear Lake 10 Apr (JCS) provided the first spring record for Lake. In recent years, spring repositioning cruises have shown Mur - phy's, Hawaiian, and Cook's Petrels to be regu- lar in our offshore waters. This year's totals of 24 Murphy's (seen on seven dates 2 Mar-12 May) and 4 Hawaiian—with 2 w. of F.I. 4 May (ph. BLS, m.ob.) and singles off Del Norte and Hum - boldt 12 May (PEL, m.ob.)—were lower than in recent spring seasons, while 141 Cook's Petrels on five dates 2 Mar-4 May represented an aver - age showing. Another Hawaiian Petrel was seen from a research vessel 47 km w. of Bodega Head, Sonoma 21 May (Kirsten Lindquist, ph. Jason Thompson). The only Flesh-footed Shearwater was seen on a more traditional pelagic birding trip off Fort Bragg, Mendocino 15 May (JCS, RLeV, ph. RAd, m.ob.). A Manx Shearwater was at Moss Beach, San Mateo 23 Apr (ADeM); this species has not been annual in spring in recent years. Completely unexpected was the north - ernmost Wedge-rumped Storm-Petrel ever re- corded, and the Region's seventh, found dead on the s. spit of Humboldt Bay, Humboldt 1 May (ph., †Deven Kammerichs-Berke; Humboldt State University 9649). F.I. hosted 2 Blue-footed Boobies in Mar, with a single bird lingering until 12 May (Point Blue). Brown Boobies were at F.I. throughout the period, with a peak of 28 on 19 Mar before numbers declined (Point Blue). Other Brown Boobies included a wintering bird continuing at Land's End, S.F. to 16 Mar (m.ob.), 2 at Trinidad Harbor, Humboldt 5 Mar, with one lingering to 8 Mar (RbF, Annie Meyer, Alexander Robinson, m.ob.), and singles at Point Pinos, Monterey 6 Mar (†DR, PFw, BTM) and Rodeo Lagoon, Marin 16 Mar–18 Apr (William Legge, David Wiech - ers). The continuing Northern Gannet entered its fifth year in the Region; it was seen at F.I. on about 20 percent of days during the period (Point Blue); and was often at Pillar Point, San WATERFOWL Lingering geese drew comment from across the Region. Single Greater White-fronted Geese were seen over San Martin, Santa Clara 19 May (Mi - chael Park), over the Pajaro River mouth, Santa Cruz and Monterey 25 May (PFw), and at Arcata Bottoms, Humboldt 27 May (ph. BEl). A lingering flock at the Sacramento N.W.R., Glenn still held 47 birds 29 May (Karen McKinley). A late Ross's Goose was at H.R.S. 14-15 May (ph. Dan Roth, ph. Steve Huckabone) and 2 were at Tule Lake N.W.R., Siskiyou 17 May (Tom Unsicker). Cack - ling Geese lingered at Bolinas, Marin through 14 May (ph. PP), at Stow Lake, S.F. 16 May–3 Jun (DMo, ph. m.ob.), and in West Sacramento, Yolo 17 May (Mark Sawyer). An Emperor Goose at Twitchell Island 9-27 Mar (JLx, JSL, ph. GaW, ph. m.ob.) was widely seen and photographed, providing the first C.B.R.C.-accepted record for Sacramento. Inland Brant included one at Ukiah W.T.P., Mendocino 10 Mar (ph. SJS) and groups of 2 (Talila Golan, m.ob.) and 12+ (Deb Vane) at Mono Lake, Mono 29 May. Of five pairs of Canada Geese at F.I., three nested and two suc - cessfully raised 7 young (Point Blue). Five of the 7 Eurasian Green-winged Teal reported were in Humboldt, with the last being noted 19-20 Apr at the Jacoby Creek mouth (RbF, Karl Bardon, JCP). A female Redhead with 2 small ducklings at Harkins Slough 15 May (ph. AMR, NLv) provided the first breeding re - cord for Santa Cruz. A male Black Scoter spent the period between Salinas River S.B., Mon - terey, and the Pajaro River mouth, Santa Cruz (Stephan Nance, ph. Nelson Samuels, ph. Jeff Roisman). A female Black Scoter was present in the same area through 29 May (Nelson Samuels, Aaron Gabbe, Craig Fosdick) and was joined by a female Long-tailed Duck at the Pajaro River mouth, Santa Cruz 29 May+ (Craig Fosdick, Aaron Gabbe, ph. Jeff Roisman). A male Hood - ed Merganser remained at Stow Lake into Jun (ph. m.ob.), providing a rare summering record for S.F. Of numerous inland Red-breasted Mer - gansers, a female at the Chowchilla W.T.P. 22- 27 May (ph. GaW, ph. George Folsom, ph. Rick Saxton, Chris Hiatt, JND) was perhaps most notable, being only the 4th for Madera, the first there since 2009, and quite late. LOONS THROUGH PELICANS The only inland Red-throated Loon was at Fol- som Lake, Placer 26 Mar (RPz). Common Loon is our most regular inland loon in spring, yet 28 at the Modesto W.T.P., Stanislaus 10 Apr (JHG, HMR, RBk) represented an unusual concentra - tion for the C.V., and one was in Tulare, where scarce, at Lake Success 11 Apr (SDS). Red- necked Grebes in Alviso, Santa Clara 5 Mar (ph. Marc Simmel) and at the Laguna W.T.P. near Sebastopol, Sonoma 18 Mar (ph. LHg) were un - Stephen C. Rottenborn Michael M. Rogers Jeff N. Davis Rob Folwer –––––––––––––––––––––––––––––––––––––– SPRING 2016 –––––––––––––––––––––––––––––––––––––– A lthough El Niño was winding down, sea surface temperatures around Southeast Farallon Island remained above average through the period (e.g., in April and May, 0.8 degrees Celsius higher than in spring 2017). Along the coast, a rainy March was followed by warm, dry conditions in April and May, whereas in the eastern mountains, April and May were cool and rainy. Highlights included two returning birds, California's only Kelp Gull (first recorded last spring) and the state's sec - ond Marsh Sandpiper (first recorded in spring 2014), as well as the Region's first spring Little Stint. We would like to extend our deep ap - preciation to Ed Pandolfino for his diligent efforts as a Regional Editor, covering species from thrashers to finches from 2006 through the winter 2015-2016 report. Although Ed's thoughtful analysis of records will be missed, his role has been capably filled by Rob Fowler as of this season. Abbreviations: C.B.R.C. (California B.R.C.); C.R.P. (Cosumnes River Preserve, Sacramento); C.V. (Central Valley); F.I. (Southeast Farallon Island, San Francisco); H.R.S.

Reports of exceptional vagrants submit - ted without documentation are not published. Documentation of C.B.R.C. review species will be forwarded to Tom Benson, Secretary, secre - Northern California Remarkably, the Region's first Marsh Sandpiper returned to the same area along the Yolo/Solano County line just over two years after it was first discovered there in April 2014. Present 16-23 April (here 21 April), it thrilled observers from across the nation. Photo by © John Sterling
