Yolo Notable Sightings: February 2021

Emmett Iverson here, taking over for Steve Hampton after twenty-some odd years of writing monthly reports for the Burrowing Owl. Steve will be sorely missed by the birding community, not only for the birds he finds but for the knowledge, skill and outreach he has provided for the past three decades.

Yolo Notable Sightings: November 2020

A mostly dry November was filled with interesting birds. Most intriguing was the appearance of two Black-throated Sparrows, only the fourth record for the county, at a private residence west of Winters on Nov 6, with at least one bird continuing longer (BG). A Red-breasted Merganser made a brief stop

Yolo Notable Sightings: October 2020

Yet another “Indian summer” provided a warm and sunny October, with nary a cloud and not a drop of rain. The best bird was the last, an adult female Vermillion Flycatcher at Woodland Wastewater Treatment Plant (WWTP) found on Halloween morning (SH). Unfortunately, it proved as ephemeral as the last,

Yolo Notable Sightings: September 2020

Despite record heat, fires, smoke, and poor air quality, migration seemed largely the same. As with any September, there were plenty of rarities to chase, highlighted by six eastern warblers. Top of the ticket was the county’s first Blackburnian Warbler, found Sept 4 at the Putah Creek Riparian Reserve (EM)

Yolo Notable Sightings: May through August 2020

There are few birds more spectacular than a breeding plumaged Red Phalarope. Three of them arrived on May 18 during a morning thunderstorm and spent a few hours in a rice paddy just north of the Davis Wetlands (JT). This was the first chaseable record in decades. A breeding plumaged

Yolo Notable Sightings: April 2020

Local birding, at least at certain locations, may have increased under the COVID shutdown, allowing many to enjoy the start of spring migration. The highlight was the county’s first ever Virginia’s Warbler, well-described on Apr 26 from the last stand of trees below the crossroads at the summit of Rayhouse

Yolo Notable Sightings: March 2020

A cool March was typically slow for rare birds. Top of the list, however, was a Dusky Flycatcher found Mar 5 in north Davis (SH). Only the second winter record for the county, the bird remained through the month, often vocalizing. A Costa’s Hummingbird display was heard several times at

Yolo Notable Sightings: February 2020

A warm and completely dry February allowed birders plenty of time in the field. The biggest surprise came on the first morning of the month with the discovery of a Lark Bunting in a large sparrow flock north of Capay along Rd 86 (SH, MP). The bird has delighted birders

Yolo Notable Sightings: January 2020

The new year featured several returning birds. On Jan 3, last winter’s Garganey was re-found at Bridgeway Island Pond in West Sacramento (LS, MS). The male is currently in eclipse plumage, but should molt as the winter progresses. On Jan 9, December’s Barred Owl made another appearance on Instagram, photographed

Emmett Iverson here, taking over for Steve Hampton after twenty-some odd years of writing monthly reports for the Burrowing Owl. Steve will be sorely missed by the birding community, not only for the birds he finds but for the knowledge, skill and outreach he has provided for the past three decades. Don’t feel too badly for Steve though, he will be moving to the wonderful and diverse state of Washington. Neah Bay in October…oh man.

February is typically one of the slower months for birding here in the Central Valley and even slower for finding rarities but that didn’t stop Yolo birders from finding a couple goodies. A gorgeous Harris’s Sparrow was found on Feb 22 amongst a giant flock of White-crowned Sparrows along Levee Road, near the Putah Creek Riparian Preserve. (KB)

A one-day-wonder Sage Thrasher (CM) was photographed at Bridgeway Island Pond in West Sacramento on Feb 6.

Earlier in the month a Red-necked Grebe was found in Lake Solano (CW, TW), this was the second one found in the span of a few weeks. Yolo birders have been waiting for over fifteen years for one and all of a sudden we had two! I guess when it rains it pours.

A presumed female Red-naped Sapsucker was found on the Solano side of Putah (RM) on Feb 14 but was seen by birders making forays into Yolo. Sapsuckers are notorious for hybridizing but early opinions on this bird are trending towards it being pure. This would represent a fourth county record.

A few continuing rarities spending the winter here in Yolo include the Eastern Phoebe at Wild Wings Park that was last reported Feb 13 (WY). The Broad-billed Hummingbird in Davis (BT, JC) has also been treating birders to views through the end of the month.

An additional note is that I have cited the observers that have most recently reported birds that were found the previous month.

Thank you to the following observers for their checklists and reports: Kathy Blankenship (KB), Chris McAllister (CM), Chris Wills (CW), Teri Wills (TW), Roger Muskat (RM), Wentao Yang (WY), Bob Toleno (BT) and Juli Chamberlin (JC).
