Posting a Diary Entry

Daily Kos welcomes blog articles from readers, known as diaries. The Intro section to a diary should be about three paragraphs long, and is required. The body section is optional, as is the poll, which can have 1 to 15 choices. Descriptive tags are also required to help others find your diary by subject; please don't use "cute" tags.

When you're ready, scroll down below the tags and click Save & Preview. You can edit your diary after it's published by clicking Edit Diary. Polls cannot be edited once they are published.

If this is your first time creating a Diary since the Ajax upgrade, before you enter any text below, please press Ctrl-F5 and then hold down the Shift Key and press your browser's Reload button to refresh its cache with the new script files.

ATTENTION: READ THE RULES.

  1. One diary daily maximum.
  2. Substantive diaries only. If you don't have at least three solid, original paragraphs, you should probably post a comment in an Open Thread.
  3. No repetitive diaries. Take a moment to ensure your topic hasn't been blogged (you can search for Stories and Diaries that already cover this topic), though fresh original analysis is always welcome.
  4. Use the "Body" textbox if your diary entry is longer than three paragraphs.
  5. Any images in your posts must be hosted by an approved image hosting service (one of: imageshack.us, photobucket.com, flickr.com, smugmug.com, allyoucanupload.com, picturetrail.com, mac.com, webshots.com, editgrid.com).
  6. Copying and pasting entire copyrighted works is prohibited. If you do quote something, keep it brief, always provide a link to the original source, and use the <blockquote> tags to clearly identify the quoted material. Violating this rule is grounds for immediate banning.
  7. Be civil. Do not "call out" other users by name in diary titles. Do not use profanity in diary titles. Don't write diaries whose main purpose is to deliberately inflame.

Please begin with an informative title:

The Daily Bucket is a regular feature of the Backyard Science group.  It is a place to note of 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.

Lake Chabot, CA

Intro

You must enter an Intro for your Diary Entry between 300 and 1150 characters long (that's approximately 50-175 words without any html or formatting markup).

My wife and I won't be available for the rest of the month and the first part of April. Accordingly, we and the other heron nest count team members decided to do an unofficial count on Sunday, March 17. We did and got an interesting surprise.

First off, we decided that at least 4 of the nests at Lake Chabot are active nests, and we counted at least 9 herons in the nesting area. While we were there, an additional heron flew into a nest already containing a pair of herons. It was almost as if, at this late date, there was competition between two males for the nesting female going on. This should be well past, as nesting begins in February. A bit later, the same thing happened in an adjacent nest. The two standing, peseumptively male, herons  at each of the subject nests were not combative, but were simply standing facing each other. This situation continued until my wife and I had to leave.

I checked several sources upon returning home and find no mention of Great Blue Herons using nest helpers. None of the team had ever seen such a thing before, and the other members hae been at this for a considerable number of years. So that's it:

Lake Chabot, CA, 3/17/2013: 4 active GBHE nests, two of which were occupied by 3 herons each during the observation period.
