The Daily Bucket is a regular feature of the Backyard Science group.  It is a place to note any observations you have made of the world around you. Insects, weather, meteorites, climate, birds and/or flowers.  All are worthy additions to the bucket.  Please let us know what is going on around you in a comment.  Include, as close as is comfortable for you, where you are located. Each note is a record that we can refer to in the future as we try to understand the patterns that are quietly unwinding around us.

Castro Valley, CA

Continued below the dodder

I have often noted that we have a Nuttall's woodpecker (Picoides nuttallii) resident in the neighborhood. Even when not in my yard, his presence is known off and on throughout the day. Because the bird is a California specialty, I decided to provide a bit of information on them.  In the process I learned that a "toss-up" bird I spotted in the distance in Anza-Borrego a while back, that I had called a Nuttalls' due to how far West it was, was almost certainly a Ladderback, due to the specific habitat it was in.

For more information, Cornell's "all about birds" page, which is also the source of some of the detail in this diary, is
here

The Nuttall's woodpecker is a small black-and-white woodpecker with a black-and-white barred back. It has white streaks on side of head and the male has red patch on back of the head.  It is primarily found in California's oak woodlands and non-coniferous riparian woods. It is only found in California.

It looks a great deal like a ladder-backed woodpecker. The ladder-backed has more red on the head and a little  more white on the face due to broader white stripes. They are pretty much identical in size range, 6.3 to 7.1 inches, or about 2/3 the size of a hairy woodpecker. Luckily, in the area where their ranges overlap their habitats do not. The Ladder-back is a bird of desert scrub.

Though the size is close to that of a downy, which runs about 5.5 to 6.7 inches, the downy has a vertical white stripe in the middle of the back instead of the horizontal stripes of the Nuttall's and ladder-backed.

These photos are from Wikimedia commons, but I had to download them and stash them in my Flickr account, for now, in order to use them in a diary. This probably messed up the metadata, so the attribution will be below each picture.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
