I felt this paper http://flow.arrr.net/penguins.pdf
Polar Biol (2003) 27: 56–58
needed a bit more publicity in the linux world

calcs based on Hagen-Poiseuille-equation

<<Whether a bird chooses the direction into
which it decides to expel its faeces, and what role the
wind plays in this, remain unknown.>>

<<Birds could theoretically increase
their projectile defaecation range by squirting 45 [degrees] upwards. However, their upright posture and position of the vent prohibit this in penguins, but in eagles and other birds-of-prey the squirt is, indeed, directed upward by ca. 15–30 [degrees] (unpublished observation).>>

The link was already posted once in LQ (I checked)
Did you know thread:

"...fully grown chinstrap and Adélie penguins generate pressures between 10 kPa (77 mmHg) and 60 kPa (450 mmHg) during the evacuation of their faeces on land." Quoted from "Pressures produced when penguins pooh—calculations on avian defaecation" http://flow.arrr.net/penguins.pdf
