Graph - Birdiness vs. Social Acceptability

Birders aren't known for being cool.  This is partially due to the inherently obsessive nature of our hobby, but also because of the, um, obscure places we tend to visit.  When was the last time your neighbor dropped by the local waste treatment plant just for the hell of it?  Never.  Because they are normal.

Our high-tech graphics department produced this precise visual representing several popular destinations, comparing social acceptability among non-birders to the locale's birdiness per acre.  It is generally frowned upon to stare into someone else's backyard with binoculars, but this awkward endeavor can yield some great birds.  In the unlikely event a birder is concerned about their "coolness", this graph can help them weigh the worth of each location before committing social suicide.

United States of Birds - All-time High Counts

Have you ever witnessed a mega-flock of birds?  Perhaps it was thousands of Red-winged Blackbirds undulating above a field, or Snow Geese congregating before a long migration.  eBird has a feature where users can observe the all-time high counts of all species within a given state.  We used this feature to find what species had been seen in the highest numbers in that state at one point in time.  For example, the report of 500,000 Sooty Shearwaters from Oregon was the largest flock of any species ever seen there (according to eBird data, which ranges from 1823-2014).  We did this for each state and plotted the species on a map using our revolutionary Birder's Conundrum mapmaking software:




Clearly, a few states have had vast flocks of some awesome birds.  Crested Auklets in Alaska, Sooty Shearwaters in the Northwest, and Red-necked Phalaropes in Maine.  Other, more unfortunate states have shitty birds like Starlings (sorry Massachusetts and Kentucky, but really?) or the Brown-headed Cowbirds in Lousiana.  In fact, the all-time high count of any species in the entire country belongs to those that Cajun flock of cowbirds.  It's probably no surprise that many of the more southerly states are represented by the rather ubiquitous Red-winged Blackbird, as many birders in the Southeast probably come across a sizable flock of these icterids at some point each year.  Snow Geese, with their habit to conglomerate en masse, also made quite a showing, filling 6 of the states.

Note: We are not saying that these counts are necessarily accurate, we are just reporting what is out there.
