Western Screech Owl at Briones

Jim Roethe
 

The Western Screech Owl was back in it usual spot this morning at Briones Regional Park.  About half way between the start of the Seaborg Trail and the first gate -- in a hole in a tree on the right side of the trail heading out.

Re: Pintail hybrid at Elsie Roemer

The educated opinions are that the odd duck is a plain old northern pintail albeit outside the norm of behavior and maturity of its nearby companions. I have changed my checklist accordingly. Thank you Alvaro, Alex, and Joseph.

This bird was basically a male pintail by plumage except for rusty sides and spotted neck. The behavior wasn't like all the surrounding pintails that were characteristically floating and dabbling. This individual was actively mucking in the grasses and such well above high water mark. It rarely pulled its head out for a view. That sounds more like shoveller behavior than wigeon. Seeking opinions.

Re: Burrowing owl

Oops. Disregard my last email: that was directions for the Burrowing Owl at Point Isabel.

The owl for Albany Bulb: not sure if it is there now. But it has been seen in the plateau area, north of the parking lot.
There is a fence encircling the plateau. In the past, the owl has been seen on the north side, near a drainage pipe on a mound.

I understand there is a Burrowing Owl now at Cesar Chavez park in the NE section of the park that has a small fence around the area.

[There is also a walkway/causeway that continues North, but don't take it]. The owl is behind the fence; not on the rocks but on a bare tree/shrub branch about 6 feet off the ground.

Easier to go during the week than the weekend, if you want a parking space.

I used to band song birds in Big Sur, and we caught many yellow-rumps (MYWA) during the wintertime that had missing feathers around their beaks, or even gummed up feathers in the same area. It turned out that there was a eucalyptus grove near the banding station, and the warblers could be seen drinking the sap from the tree's flowers. Their bills weren't designed for that and they got sticky residue all around their bill. Hummingbirds did the same thing and didn't have that problem.

Dear Isabelle,

Flowering eucalyptus are a source of nectar for birds (and insects), but our small-billed wintering birds do not appear to do well because they get a gummy deposit on their faces from the flower nectar and eventually the feathers fall off.  Some are able to handle this okay, partly because those feathers are replaced towards spring in the prealternate molt.  Others, perhaps not.  Long billed nectar feeders, like our hummingbirds do not have this problem as they don't get sticky deposits on their feathers, just their bill, and that can be cleaned off (there are many nectar feeders in Australia and they all have long bills).  Other birds, including wintering tanagers, more often prey on the insects attracted to the nectar, and they don't have the same problems.  In my experience this is a common phenomenon, particular for warblers and kinglets, and it becomes progressively worse during the winter season.  It is not a disease as far as I  know, just the result of an individual's feeding preferences.

Hello,
Recently, I mentioned that I found a strange Ruby-crowned kinglet without feathers around its beak. Yesterday, I found another bird (this time a yellow-rumped warbler) with the feathers around its beak gone. It was in Pleasanton, in the canal that borders Val Vista Park. In this case,  it seems that the feathers above the beak are growing back but under the beak it is still very much exposed. Could it be a disease or some other causes, like parasites or some type of sticky surface the bird encountered while eating. I hope it is not something in the environment that caused it. Any idea? See my ebird listing for 4 photos. Thank you and have a nice weekend.

I had 15 in Alameda near the ferry terminal maybe two weeks ago in one spot (they continue there) and a day or two later 22 together on Putah Creek.

Having not made it to the park this morning, I took a late spin around on my bike.  I noticed what I seemed to be a male Hooded Merganser hiding amongst the Buffleheads, so rode around the big pond to see them closer.  By the time I was at a good place, they had landed back where I was when I first saw them.  So I went back to my starting point, counted 10 female and 6 male Buffleheads, with no Hooded Merganser.  Hmm.

 

I went the rest of the way around the pond and rode to the entrance of the private Seven Hills School.  The smaller concrete pond over there is the irrigation water for the park.  Seventeen Hooded Mergansers were on that pond.  Derek, did you not report a high number for you recently?  

 

I thought that was pretty good.  I am not sure we have ever seen that many even at Lake Solano on Putah Creek.

 

Meanwhile, the hugh number of Ring-necked Ducks I had last Saturday s down to four late today.

White-throated Sparrows

Douglas Vaughan
 

I had inferred three WTSPs earlier this fall but was certain of only two. This morning four appeared together on our patio. This species has been regular for us for two decade, but numbers have increased recently (five last year). This seems to support the notion that immatures follow parents to their wintering grounds.

Purple Finch - Antioch yard - 12/9

This morning we had a stunning male Purple Finch in our bird bath. Yesterday, we watched a female there. In addition, we continue to get a Fox Sparrow, Hermit Thrush and a single Pine Siskin joining the other birds at the feeders or bird baths.

Happy birding.

December eBirder Photo Challenge

David Yeamans
 

Ebird's ebirder of the month challenge (to qualify you in a lottery drawing for a pair of $3k binoculars) is to post checklists with at at least 50 rated photographs summed over all checklists in December. I've accomplished that handily so it struck me to see how many different different species I could photograph in December in my county. I'm up to 88 and am about to go find some woodpeckers, turkey, kingfisher, and red-winged blackbird. An easy way to find an approximate sum of my December photos is to go here:


Not all photos are great but that's the nature of a limited hunt criteria.

California has another chance to observe the King Tides on December 13, 14, and 15. If you are able to safely visit the shoreline during these highest tides of the year, your photographs will help preview the impacts of sea level rise and understand how our shoreline is affected by high water today.

During the November King Tides, more than 600 photos were uploaded to the project. You can see them mapped here, and the photos you take during the December King Tides will be added to that same map. If you can help us fill in the gaps, that would be fantastic, but it's also helpful to get multiple photos of a location.

Find your local King Tide times and learn how to upload your photos on our website or with a free app. It's easiest with a smartphone, but a digital camera works too! Most importantly, please be safe: wear your mask and maintain distance from those outside your household, watch out for wildlife, and always respect the power of the ocean. As part of the latest COVID-19 restrictions, Californians are instructed to stay close to home, but are encouraged to maintain physical and mental health by safely going to a park, a beach, hike, walk, or bike ride with members of their own household. Please only take photos for the California King Tides Project if you can safely do so.

What causes sea level rise, and what do King Tides have to do with it?

The sea level rise we're experiencing now and will experience in the future is caused by burning fossil fuels like coal, oil, and natural gas. Carbon dioxide in our atmosphere acts like a blanket, trapping in heat that would otherwise escape. When we burn fossil fuels, we're adding more carbon dioxide, "thickening the blanket" and warming the planet and ocean. Sea level is rising because land-based glaciers and ice sheets are melting into the ocean and also because water expands in volume when it warms. The amount of sea level rise we will ultimately experience depends on how quickly we stop burning fossil fuels.

King Tides themselves are not caused by sea level rise, but allow us to experience what higher sea level will be like. King Tides are the highest tides of the year, about a foot or two higher than average tides, which corresponds to the one to two foot rise in sea level expected during the next few decades. When you observe the King Tides, picture the water level this high and higher every day. Understanding what a King Tide looks like today will help us plan for sea level rise in the future.

Sharing your photos and talking about what you've noticed helps us all understand we're part of a community that cares about climate change and wants to act to protect the people and places that we love.
