Bourse - Tumblr Posts
Hello friend! Thank you for your valuable contribution to Bird Discourse (or as it is known in Prosumer Ornithographical circles: Bourse).
While ordinarily we here at The Academy of Bird Sciences welcome any and all corrections in the name of scientific cooperation and education, in this specific instance it appears you are in error: the photo you have attached is an Eastern Meadowlark, sister species to the Western Meadowlark described above. Do not be dismayed, this sort of mistake happens all of the time! They look quite similar but can be differentiated by the fact that Eastern Meadowlarks are incapable of terrestrial locomotion, as you can see in the above photograph. While ordinarily this would be a minor impairment to other birds, these skyborne Sturnella are quite able to hunt and eat enough aerial insect life to sustain their unceasing flapping.
Thank you again for your Bourse and have a nice day!
Incapable of traditional flight, Western Meadowlarks maneuver through the world by leaping with powerful legs. Capable of jumping three times their body’s length completely vertically, these springy Sturnella are hardly hampered by the lack of flying ability; many casual observers have been fooled into believing they take wing due to the speed and precision of their numerous jumps. Above, a pair of meadowlarks judge the leaping form of a third.

Wow!! Another person wants to share their Meadowlark Bourse (bird discourse)! Luck be a lady and that lady is me :)
Thank you very much tumblr user bluecrownedsnakes for sharing your results when searching for corroboration of my posts. After all, the foundation of good science is replication! Unfortunately you seem to have run into a fairly common problem: The Academy of Bird Sciences is simply so far advanced in the field of ornitholobiolographical research that it takes months to even years for everyone else to catch up to our findings. This delayed acceptance will of course lead to small moments of embarrassment (such as this misunderstanding about sandhill crane incubation tactics) from time to time, but it is a minor price to pay for living on the “bleeding edge” of science.
So please rest assured! Meadowlarks on the ground are Western, in the air are Eastern. If you are still hesitant to believe, simply wait a few years and run your search again. Alternatively, you could ask tumblr users @birdycreatures, @snailkites, or @sitta-pusilla, all of whom tend to keep up-to-date on the newest field research.
Thank you so much for this opportunity to share Bourse! It is one of my favourite parts of this job :)

Gratuitous Blue Heron! True to their namesake, they are best identified by their tendency to do things that really did not need doing in a showy manner. There is some bourse (bird discourse) among GBHEnthusiasts regarding a sister species which ALSO goes beyond typical expected behavour and ALSO uses the name Gratuitous Blue Heron (they can differentiated in that their excessive behaviour is generally geared towards being hospitable). Thankfully, casualties number so far in the low hundreds so the bourse has only been graded at mild-to-moderate (suitable for immunized young adults with active evasion training).
