C. melanotes
of the ♂ when I flushed her, but
birds are not strongly aroused. this
matter of sex ratio remains puzzling.
Granted ♂ are more conspicuous than
♀♀, but we have seen many more
♀♀. ♀♀ couldn't have got onto eggs
that quickly - I can't even guess
where they are.
22 June
Saw 4 ♂ and 1 forborn ♀ on
low marsh or lake side of Holmes'
Herowick plot. a few half-heated
hoots and chases, but certainly not
intensive breeding activity. Later
found one ♀ (SM 117 feeding obs.-collecta)
well into incubation, and a pocket
of 3 ♂♂. No sign of aggression
within the ♂♂, although one collected
has t = 12 x 6 mm. Later collected a
t = 10 x 5 mm ♂. I don't think there
is much breeding activity going on right
now - possibly this cola spill has
interfered.
24 June
On Holmes' Marass saw 3 ♂♂
feeding within 20 m. of each other for
nearly 30 minutes with no signs of
aggression or any indication of interest
in breeding.
