Mar. 7 Heather Farm in the crisp morning

It was a glorious day, despite the crispness of the morning.  Great birds today and some new faces walking, including Jim{?} and Julie from Danville.  Their son at school at Purdue told them to visit Heather Farm for the Wood Ducks.  We found them.

A Kingfisher was on the trees of the island, a Red-shouldered Hawk flew, called and maybe landed in the eucalyptus trees at the north parking lot.

Five sparrow species and a Sora came to some seeds just a bit north of the gap where the river otter crosses the sidewalk and leaves its mark.  A Marsh Wren was singing in the reeds at the same location.  The Lincoln's Sparrow here is one of three seen today.  Two Fox Sparrows were at the otter crossing, too.

Red-winged Blackbirds were singing in two or three locations.  Bushtits were active, as were the Yellow-rumped Warblers.  The most active birds were the Canada Geese, who were honking, flapping wings and pushing each other around.  Ring-necked Ducks, a couple Buffleheads, including a male, and Coots were also on the big pond.  Up to six Ring-billed Gulls were around, too.

Rufous Hummingbird

Johan Langewis
 

This morning a male Rufous Hummingbird visited my feeder. The back was completely orange, not a fleck of green to be seen. No Allen’s in my yard yet. Also, a Chestnut-backed Chickadee started nest building in my nest-cam box today. Sure signs of Spring. I’m waiting to see if the Brown Creepers will return to the same nest site they used the last three years. Also waiting to see nesting activity of Nuttall’s Woodpecker, Bewick’s Wren, and a few others. I minimize my observation of nests so I don’t alert the local predators, especially Corvids. I hope everyone keeps this in mind this Spring.

Two morning visits to Heather Farm March 5

rosita94598
 

It was worth it to make two visits this morning, though the first was before 6 AM.  I walked over with a scope to see the conjunction of Mercury and Jupiter.  Couldn't see them, very few stars and worried about whether I was too late, the sky a little too bright and the half-Moon above.  But when I walked out onto the north ball field through the dugout, bang, there they were just over the right shoulder of Mount Diablo.  I was actually too early!  The hot chocolate back home at 6:10 was a nice picker-upper.

Before 7:30, I went again for the birds and on my bike.  Fifteen Cedar Waxwings were in a tree before I even made it down our street to the Contra Costa Canal.  A Marsh Wren was singing like crazy in the reeds just north of the gap where the otter poop is often visible on the west side of the large, mostly natural pond.  This morning some very fresh poop was there and the sidewalk was wet where the otter had crossed to the currently dry Ygnacio Canal.

The Wood Duck pair was visible near the island from the wooden railing below the parking lot.  A Common Gallinule was also there, standing close to a Snowy Egret.  The Ring-necked Ducks are sticking around, but there are only a handful of Coots and maybe two female Buffleheads.

I did not go to the entrance of the private Seven Hills School today, but yesterday two or three Rough-winged Swallows were still flying over that pond. Twelve to fifteen Ring-necked Ducks are also hanging out there.

A couple of Red-winged Blackbirds are also staying, now, singing their cheery songs from the reeds or trees around the large pond.

Red-tailed Hawk at Arrowhead

Claude Lyneis
 

This afternoon there were some interesting birds at Arrowhead.  I saw a Belted Kingfisher hovering and diving into the marsh area.
A presumed Red-tailed Hawk landed in the field, in a tree and flew around a couple of times.  It looks slightly different from others that I have photographed, but Red-tailed Hawks  seem to have a lot of  variety in their markings.

A couple of photos of the Red-tailed Hawk are at this link. https://flic.kr/p/2kH63WT

That’s a Swamp Sparrow! Great bird! (Though maybe not quite as good as that Vesper you found at Mines Road?)

Great Common Gallinule shot too.

Re: Where are the Lake Merritt Scaup?

Joe Morlan
 

Jim,

There is a direct correlation between reduced numbers of ducks and the
discontinuing of the twice daily duck feedings at Lake Merritt a few years
ago, due in part to some people’s complaints that the birds were not
migrating (not true), and also to a lack of city funds. In addition there
have been additional claims that feeding ducks is bad for them and
unfortunately several government entities have bought into this false
narrative. E.g. duck feeding is now banned with enforcement at the famous
Palo Alto duck pond with the predictable result that most of the ducks are
no longer there.

More on the controversy from across the pond....

Work took me to lake Merritt today and I looked at the lake from two areas quickly and saw less than 60 scaup. Intrigued, I looked at ebird Lake Merritt sightings this month and I think the high scaup number (both lessor and greater) is 100 and for the winter 250 or so (one report - thanks Alex). The areas I looked included two of
the three spots the large flock usually was. Past years, I think the lake, would hold a flock of 250 to 500 or so all winter (guess on my part)

So, I ask the question? Did I miss the big scalp flock since I did not scan the entire lake?

Or is the flock not there as the eBird reports - or do people just look for the barrows goldeneye and then are done - but has anyone birded the entire lake to establish the scaup flock size?
I worry that maybe one of the following could be occurring:
1. Lake Merritt is changing and the habitat is not holding scalp as it used to.
2. Scaup numbers overall are down - I don't bird the waterfront much these days so I do not have a sense of scaup numbers on the bay
3. Scaup are not using the lake in February

Does anyone have historical scaup flock sizes for lake merritt so we can track the flock size and where we are this year. Lake Merritt is one of the birding gems of the east bay and it would be good to know the scaup flock size as they are one of the "keystone" wintering species for the lake.

If anyone does a comprehensive scalp lake survey - can you send me your totals offline in response to this post? IT probably would be good to note it as a comprehensive lake survey in the ebird list comments - we need one of these at least every year and month if someone uses the lake as a local patch - its too far from home for
me.....

I did see 8 red-breasted mergansers on the lake and I think this is a high end number for this species on the lake. I like seeing big scaup flocks on the lake in winter. This is where I learned to recognize greater scaup from lessor scalp by the nature center so it is a special place for me (and there still is a mixed group of
greater and lessor scaup coming in for food.....).

Thanks,
Jim Chiropolos

( PS on the topic of decreasing duck numbers I did not look for Barrows Goldeneyes in the channel but it has saddened me how from over 10 or more using Barrows Goldeneye were present in the winter in the channel about 10 years ago we are maybe down to one pair or so with numbers seemingly decreasing every year . The Merritt
channel human habitat is very different from 10 years ago...…)

Cedar Waxwings.. toxic berries?

alisonG
 

At least 8 Cedar Waxwings were found dead, close proximity and no external injuries, at the Claremont Golf Course.
Not clear if a plant/berry is responsible or some other toxin in the area. 
For example, Heavenly Bamboo(Nandina domestica) berries are toxic and CEWAs are known to fall victim poisoning.
I don't know if the Claremont GC has these non-native plants on their grounds. 

Has anyone recently encountered dead CEWAs lacking external injuries?
GGAS, Lindsay Wildlife, Cali F&W have been contacted.
The Claremont GC has been notified. The CGC state that they are "very environmentally conscious, use organic fertilizer, have a special area for bees etc." They have asked to be kept informed.

Saved a couple CEWA specimens if further analysis is needed.
heartbreaking... they are such elegant birds.

Re: Long or Short-billed Dowitcher

Claude

    Was it in fresh water? That looks like a Long-billed, because it is on the very long billed side for a dowitcher. Well over 2 head lengths, nearly 3. As well barring on the flanks looks good, but I am not sure how reliable that character is.

Today, out just north of Pt. Isabel I was getting close to photography some of those tiny peeps, but in the process I got some photos of Dowitchers and remembering the earlier post Jim Chiropolos stating that most are short-billed in the bay, I hesitate to ID it as a Long-billed Dowitcher.  Still that is how the iNaturalist artificial intelligence software I.D.s it.  So I leave it to the EBB experts.  Either way since it was not posted to eBird, it won’t upset the bird counts.

Anna's Hummingbird with pigment issue; pink bill

Susan Greef
 

Hello all,

My birding friend Chris Carmichael invited me to a private home in Berkeley this weekend to see an unusual hummingbird he had spotted; a female with a very pink bill.  While enjoying watching her beginning her nest building, we speculated on what might be going on with the bill color.

My pictures got the attention of Sheri Williamson, ABA's go-to person for all things Hummingbird.  She identified it as an Anna's with an interesting pigment issue.  As this bird is residing in a private home, location cannot be divulged but here are a few of my photos out of interest:

Hairy Woodpecker - Contra Loma Regional Park, Antioch - 3/1

Paul Schorr
 

Today Nancy and I located the Hairy Woodpecker that Jerry Britten first reported on 2/19. We first located the bird at 10:45 and watched and photographed it for about one hour. The bird was very active in the trees along the west shore of the reservoir. We first found it just north of the small inlet about half the distance to the dam. It flew across the inlet and we located it again in the trees south of the inlet. Photos are included in my eBird posting.

In addition, we saw a single Tri-colored Blackbird in a flock of Red-winged Blackbirds. Total species for the day was 43, a nice way to start the month of March. With the addition of the Hairy Woodpecker, our total species at Contra Loma R. P. is 151.

Happy birding.

Help with ID

Rosemary Johnson
 

On my walk in Hercules neighborhood this morning, I saw an interesting bird that I couldn't id and neither could Merlin to my satisfaction. Laugh because Merlin was what I first thought by size, shape and coloring.  I should mention that I mostly saw the bird from the back.
 
It had a mottled brown and white back, more of a solid brown head and a black tail.  But here's the interesting part. It had a definite red cap that I saw when it turned its head.  The app suggested a Bohemian waxwing which the coloring was similar, except for the white speckling, but body type was not.
 
Any ideas?  Sorry, when I tried to take a pic, of course, it flew.

New Yard Bird - Downtown Berkeley

Don Simonson
 

An Orange-crowned Warbler in our backyard near downtown Berkeley BART stop was yard bird #47.  While common here, this species is a rare skulking find in my native Maryland so it was fun to see it in the clear. it rested in a birch while the local Anna's Hummingbird hovered a foot away for a minute or two, giving it the hairy eyeball.
Good birding!
