Thanks, T40.  Those measurements/comparisons are interesting.  I confess, from the illustration, I am unable to determine the difference between the "Bill Culmen" and "Bill Gape" - they look to me like the dotted lines are pointing to the same spots in that drawing for those two measurements.  Maybe I just need a larger view of that drawing to see what is different about those two.

baz - The gape is measured from commissural point to commissural point (i.e., the edges of the mouth). It's the widest part of a fully open mouth.



The culmen is measured from the tip of the beak to the bottom of the cere, which is what they're referring to as "Bill Height," for some reason. It should be called "culmen length," which is a chord measurement used for sexing eagles. (see attachment)

What they're calling the culmen is a measurement I couldn't find anywhere but it seems to measure from the tip of the beak to the commissure.

Thanks, T40, but I understand the Bill Height (culmen length as you referred to it today) measurement.  The illustration you posted yesterday includes another different measurement, called the Bill Culmen - it is different from the Bill Height (aka culmen length), and in the illustration from yesterday, it appears to point to the same spots on the Harpy that the Bill Gape points to (I know what the Bill Gape is measuring).  That's what my post was about...  ;)

 baz - I know. Sorry if that wasn't clear. I searched for their so-called bill culmen measurement and couldn't find it anywhere. Don't know what it's used for or how long it's been in use or not in use. Nothing. All I could do was speculate as to what it looked like the bill culmen measurement included, because I disagreed with what you see in their drawing, confusing as some of it is.

I tried to differentiate the gape from the bill culmen. The gape is from corner-to-corner of the mouth, with the bill not even considered.

LOL T40... thanks for trying...  if only I could actually say it out loud  ;) :D  ... LOL...  In the illustration you posted yesterday, at the top are the words "Bill Culmen" - I was thinking the dotted lines the "Bill Culmen" label is referring to were from the mouth's corner-to-corner - same as in the "Bill Gape" dotted line - But there are different measurements for both the "Bill Gape" and the "Bill Culmen" listed below that illustration - in addition to, and separately from, the "Bill Height" (aka culmen length) - so I know they are all three separate measurements, as listed directly below yesterday's illustration.  But now, as I look longer at the dotted lines there for "Bill Culmen," I am wondering if it is trying to point to the distance between the ridge of the beak at its outermost point from the face to the corner of the mouth... yes, I think now that is what it is trying to indicate in that illustration for the "Bill Culmen."  Ha ha... Clear as mud, right?  ;) :D

Research communication: Dispersal of Philippine Eagles Released in the Forests of Mindanao, Philippines (Dec. 2015)

(The English and Filipino translations get sort of mixed up together, but all the information is included. It's just a layout issue.)
