The first month of 2018 started off with some real surprises. Two of them were firsts for the Central Valley. ACurve-billed Thrasher, apparently of the eastern sub-species group, became widely known on 1/14 along Rominger Ct in Woodland, not far from the Woodland WTP (https://ebird.org/view/checklist/S41922675). It was seen and photographed by many visiting a residential yard into February, but had first been detected by a resident on 1/8 and word got out when it was entered on eBird. The other amazing find was a Worm-eating Warblerat Reichmuth Park in Sacramento from 1/6-29 (https://ebird.org/view/checklist/S41846248and https://www.flickr.com/photos/conardc/24806666407). Despite being a secretive bird, often staying low and in dense vegetation, it was seen by approximately 150 birders. Both of these species are on the California Bird Records Committee review list (http://www.californiabirds.org). Unpleasant surprises included a human body found by birders looking for the Worm-eating Warbler and a group of birders visiting the north Valley who had their car set on fire while only a short distance away.
An immature maleCosta's Hummingbirdwas reported on 1/12 at Reichmuth Park but was not refound. Adding to the reports of winteringCassin's Vireosthis fall and winter was a bird found at Cosumnes River Preserve (CRP) on 1/22. A Winter Wrenwas heard calling and recorded on 1/28(https://ebird.org/view/checklist/S42324399)from the same closed portion of CRP where one was found in November of 2011. TwoPacific Wrenswere calling nearby for comparison. A Northern Waterthrushwas an excellent find along Putah Creek on 1/4 near the Hwy 128 bridge over Putah Creek in the area that often hosts anAmerican Dipper. The dipper was seen occasionally too, and the waterthrush continued through the end of the month. The Palm Warblerfirst found at the Woodland WTP on 11/24 was reported into February. TheSwamp Sparrowfound just off the auto tour at YBWA on 11/25 continued into late January. The continuingHarris's Sparrowalong S Meridian Rd in Sutter County was reported through at least 1/22. A Red Fox Sparrowwas found along with twoSooty Fox Sparrowsalong the Sacramento River off of Riverside Blvd near 35th Ave on 1/13 (http://ebird.org/ebird/view/checklist/S41876558) and a maleBlack-headed Grosbeakwas a real surprise for winter in Land Park on 1/18.
The Sacramento Area is roughly defined as lying between Hwy 20 to the north, Hwy 12 to the south, and the 1000’ contour to the east and west, plus all of Sacramento and Yolo Counties. Many reports first appeared on the Central Valley Bird Club Listserve (cvbirds.org) and in eBird (ebird.org).

Thanks to everyone for their reports—without them, this column would not be possible.
