Ring-bill  May 10, 1955
III

This "Waaaaa-waaaaaa-waaaaaa....." O call is presumably the exact homologue of the PCG of Franklin's Gull 

Scheme in both species somewhat as follows
[[image]]
Aggressive pumping 
Long Call          
Oblique
[[dashed lines link up & over to]] Choking 
[[solid lines link down to]] Long Call Oblique

Plaintive
Muffled
Less aggressive pumping
Long Call Oblique 
[[dashed lines link up & over to]] Choking 
[[solid lines link down to]] Long Call Oblique

Partly Sexual Groan
Oblique-Low Oblique 
[[dashed lines link up & over to]] Choking 
[[solid lines link down to]] Long Call Oblique

How do the HD,TT, and L (with LC) patterns fit in?

[[in margin - cross hatch doodle]] T is obviously more (or less) than purely sexual in this species

[[in margin, 3 vertical bands & cross hatch doodle]] Females seem to be as aggressive as males in territorial defense.
