Web wide crawl with initial seedlist and crawler configuration from March 2011. This uses the new HQ software for distributed crawling by Kenji Nagahashi.
What’s in the data set:
Crawl start date: 09 March, 2011
Crawl end date: 23 December, 2011
Number of captures: 2,713,676,341
Number of unique URLs: 2,273,840,159
Number of hosts: 29,032,069
The seed list for this crawl was a list of Alexa’s top 1 million web sites, retrieved close to the crawl start date. We used Heritrix (3.1.1-SNAPSHOT) crawler software and respected robots.txt directives. The scope of the crawl was not limited except for a few manually excluded sites.
However this was a somewhat experimental crawl for us, as we were using newly minted software to feed URLs to the crawlers, and we know there were some operational issues with it. For example, in many cases we may not have crawled all of the embedded and linked objects in a page since the URLs for these resources were added into queues that quickly grew bigger than the intended size of the crawl (and therefore we never got to them). We also included repeated crawls of some Argentinian government sites, so looking at results by country will be somewhat skewed.
We have made many changes to how we do these wide crawls since this particular example, but we wanted to make the data available “warts and all” for people to experiment with. We have also done some further analysis of the content.
If you would like access to this set of crawl data, please contact us at info at archive dot org and let us know who you are and what you’re hoping to do with it. We may not be able to say “yes” to all requests, since we’re just figuring out whether this is a good idea, but everyone will be considered.

Wonderful photos!! I'd be excited too!! LOL!!!
Beautiful photos. I wish I had your eye for shots like that.
I believe the birds feel your love Shelley!
Awesome pictures. Taking flight, due to your noise, can't get better than that.
They are fleeing YOU...they are still gorgeous.
xo
Of course they like you! What's not to like! Great pictures, Shelley. :)
Wow. Those photos - and the subjects - are incredible. Just fabulous, dear! :)
Gorgeous shots, Shelley! Happy weekend!

Hope you have a great weekend!
*hugs*

Wow!! I love these shots.
I'm no 'tenderfoot' in the woods either. I asked my Hubby to help me build a blind so that I could get some new Turkey shots....and said 'What's the point...you wont be able to stop figiditing around long enough to get any photos.
Love those pictures, Shelley...nothing prettier than birds in flight!
AWESOME photos....thanks for sharing.
AMAZING photo!! We have an eagles nest near our property in Presque Isle County, and managed to get some great video. Love it!!
I am sad about Miche Gross.
Love those pics
I guess you did not scare them ALL away (o:
Great pics Shelley, as usual. I love the bald eagle in particular. We seem to have more crows than anything around our place, although this year we did have a pair of wood ducks hanging around the cove for awhile.
I like action shots better than still shots, especially in the setting in which you captured these pictures. The one of the mallard is so color coordinated that it looks staged. Keep making noise and capturing beauty.
