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.


  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 Green Heron (Butorides virescens) is a common migrant and summer resident here in south-eastern Wisconsin. Arriving between mid-April and late May, these flashy little waders choose to nest secretly and in solitude, or sometimes in small, loosely associated colonies on quiet wetland islands in marshes or along pond shores and slow flowing streams with rich habitat.

This spring I noted my first 2012 sighting of a Green Heron down on the bend of the river on May 31st.

Masters of concealment.

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).

I love old literature [Birds of America, 1936].

Green Herons are dismissed by some as gawky, awkward, and rather stupid birds with habits that are not exactly tidy. This is because he is usually only seen when he utters his harsh alarm note and flops clumsily along to a nearby perch, where he stretches his neck, jerks his tail, and gazes around in a fuddle-headed manner.
Ouch! Fuddle-headed? That's a bit harsh.

The only real requirement a Green Heron seems to have is some modicum of cover in the wetland. Indeed, this species is so adept at concealing itself that its habit of flushing suddenly from hiding with a loud cry and a stream of white excrement has given it a number of colorful common names – 'skeow', 'fly-up-the-creek', 'chalk-line' and 'shite-polk' are a few of my favorites. I'm thinking, maybe this brisk release of white bird-poo, just might be a predator diversion program. Or maybe not.

The legs of the male turn orange when these little loners pair up. His mate will lay 3 to 5 pale sea-green eggs on a frail nest platform of loosely piled sticks and twigs in a tree or bush, near or overhanging water. Both parents share nest building and incubation duties, with the eggs hatching in about 20-21 days. Green Heron pairs remain monogamous throughout the breeding season.

The youngsters leave the nest at 16 or 17 days post-hatching, are flying at 21 to 22 days and are self-sufficient and independent by the end of 30 to 35 days. Their parents often raise a second clutch.

Far from being stupid or clumsy, these stealthy little stalkers thread their way silently through vegetation to fish the shallows. They use favorite perches just above the water and visit raised rocks or turtle basking logs.

They pose motionless, waiting long moments for prey to come within striking distance. The strike is lightning swift and accurate. How do they stuff that long sleek neck back into that stubby body?

These wily little herons are opportunistic feeders, feasting mainly on small fish. Frogs, leeches, worms, salamanders, bugs, crayfish, snakes and other great side-dishes are also on the menu.

Apparently, Painted Turtles aren't.

Green Herons are one of the few birds that use tools. Some have been observed using feathers, broken sticks, earthworms and insects as bait to draw small fish in closer.

Clever, clever, tool-using bird!
