Re: Bradford Island today (6/1) and a little bit of some other places.


I thought the conclusion a long discussion string a year ago- Bradford is a private island and access is by invitation only.

Subject: [EBB-Sightings] Bradford Island today (6/1) and a little bit of some other places.
Date: Saturday, June 1, 2019, 7:08 PM

Birded the delta from about 7:30am to 2pm
with sharp, young birder Lucas "I have really good eyes"
Conducted a Christmas Bird Count-style
census of Bradford Island, walking most of the island and
keeping running tallies of all birds.

While waiting for the ferry to depart,
we heard singing from the willows to our right a single Chat
and Blue Grosbeak. Not much else.

BRADFORD 8am-12pm.  (
Circumnavigated the island
counterclockwise. From ferry, we proceeded North along the
levee road. Halfway up the island, we turned to the West,
driving about ¾ of a mile into the middle of the island
before turning North. Drove until reconnected with levee
road. Proceeded to the left, counterclockwise until the
ferry. Along the Central Road and East levee road, we walked
most of the distance along the side of the willows. Notable

1 BELL’S VIREO heard singing was
possibly a returning bird, although it was singing along the
North end of the Island’s central road, as opposed to the
two Bell’s that resided right next to the levee last year.
If this is a returning bird, it has moved about 1.5 miles
from where it was previously. I highly encourage everyone to
check the original location (38.0690643, -121.6493793) for
vireos in the following days to confirm if this singing bird
is a different individual.

*Possible REDSTART chipping and seen
briefly here: (38.0802946, -121.6636102). We only saw this
bird once for a fraction of a second before it disappeared
into the willows, so I don’t feel certain calling it, but
I am not certain as to what else it could be. A warbler
flipping a seemingly long tail, calls like a Yellow. I could
make out no colors or patterning, and I just saw the bird's
tail end.

18 YELLOW-BREASTED CHAT is a new county
high count (the previous count was 8, I believe). This was a
very careful and meticulous count of the island’s chats.
In three separate spots we had 3 easily detectable at once.
We saw 8, maybe 9, the rest were singing non-stop. Chat song
was ubiquitous this morning. Some of these birds might be

3 Willow Flycatcher. 1 along levee road
(in old Bell’s vireo spot) and 2 along the Central road in
the willows. Should be investigated as a possible breeder.
1 Tricolored Blackbird. Flyover male.
2 Allen’s Hummingbirds. Small colony
like on Bethel on North side of Island.
3 Black-chinned Hummingbird, 2 males
and 1 female were at different locations around the island.
4 Western Wood-Pewee. Apparently the
first hotspot record. Very vocal.
6 Blue Grosbeak
5 Ash-throated Flycatchers
1 Swainson's Thrush
2 Pac-slopes
10 Yellow, 1 Wilson's and 1
Orange-crowned Warbler

To access island, buy $7.50 ticket at
Oakley Valero. Ferry times posted online, just do a search
for Bradford Island Ferry. (If you decide to bird here, be
careful. Few people will bother you if you stay on the
levees but be careful with where you point your camera. Walk
off the levee at your own risk.)

PIPER SLOUGH 12:30pm-2pm. (
Walked the willows at Piper Slough.
Fairly quiet.
1 Pewee, 1 Willow Fly, 1 Yellow, 2 Blue
and 3 Black-headed Grosbeak, 1 Ash-throat, 1 Warbling Vireo,
in terms of migrants. We also had several kettles of
Swainson’s Hawks pass over head, totaling to a counted 43

Good birding,
Ethan Monk
