Well if you have mates like Dirk Pons who once spent at least half an hour of a hike along the Drakensberg escarpment with me calculating (in his head no less) the coefficient of lift of a Lammergeier, you may just have.
Bronwen Kausch sent me this gem.
And in case you were feeling short-changed… Jonathan Corum throws in the capitals of Assyria as well!
Now you have had your dose of useless information for the day.



This was indeed the European (Hirundo rustica) Peter, the kinematic data for the African swallows (Hirundo domicella and Hirundo spilodera) apparently being in short supply!
Now the question that my brother asked via email was "what exactly is a laden swallow?". Is it one that has not (swallowed that is), one that has recently evacuated its bowels, or one that is merely carrying mud to its nest? :) Mr Corum is not clear on this point.

Ahh! but was it an African or a European swallow?
