Mixed Diglossini, Sept 24, 1962, IV

[[margin]] Glor [[/margin]]
The two birds then hop thru shrubbery. ♂ following ♀. ♂ repeatedly accelerates to chase ♀. Almost “pounces” (but horizontal). Some of these silent. Others with "Sraaaaaaaaa"s ("R"s). One with R- Eeyah.

[[margin]] Glor [[/margin]]
Both fly off when car drives by. ♂ back alone. Singing again, as before. Penultimate R components. Sings from different perches "Patrolling". As far as I can tell, his songs are identical with those of many aterrimas. "Zewa" components hardly recognizable.

Both birds apparently gone now 7:40.

I shall call this pair "X".

[[margin]] Glor [[/margin]]
I think the X birds were behaving the same way yesterday; but I ignored it, presuming that their reactions to one another were a boundary dispute.

[[margin]] Glor [[/margin]]
Walk away. Come back 7:47. See X ♂ sitting quietly on perch. Then he flies up (as a result of seeing me), goes quite high up in air, utters song in flight then lands somewhere else.

So this subspecies has "aerial display" too.

[[margin]] Glor [[/margin]]
It is obvious, I think, that ♂ & ♀ Glors do tend to stay together, or at least come together frequently, at the height of the breeding season.

[[margin]] Glor [[/margin]]
♂ X singing much less frequently now, 7:52, altho I don't see the ♀ around anywhere. Oh yes! Now I see them both. One chasing the other again.

[[margin]] Glor [[/margin]]
Again surprise X ♂ while he is sitting alone and quiet. Again he flies up to give aerial display. Goes very high, but in a broad arc
