PaudurHill (Nepal) Raptor Migration Update 30Sept – Day 15
Now I am down to Chitwan to attend the national red data
book workshop of birds it is going to start from tomorrow 1 Oct. my colleague
Surya Gurung is up to the hill for the migration counting. In last two days we
had an exciting migration of Barn swallows and Red-rumped swallows more than
2000 birds. Mostly swallows are migrating before noon. The weather is going to
be terrible again due to thick cloud very close to the ground. The northern
ridge was completely covered with the cloud mainly after 10:00. Other migrants
were Black Kite, Booted Eagle, Peregrine, Eurasian Hobby, common Kestrel,
Oriental Honey Buzzard, Common Buzzard etc. These species will be continue in
this week also. The Dragonflies migration is also continue. I got an email from
my Colleague Bob regarding dragonflies
according to him;
Probably a species of Pantala...could be this one:
wandering glider (Pantala flavescens)
http://en.wikipedia.org/wiki/
Their arrival in the subtropics and tropics coincides with the Intertropical Convergence Zone.[18] More evidence of their preference for moist winds, is that the dragonfly migrates to Southeast India's Tamil Nadu only after the second monsoon which is brings the rain to that region. In the rest of India, however, it arrives with the first rain-making monsoon.[16] Observations suggest that they migrate from India to Africa across the Arabian Sea.[19][20]
It is the highest-flying dragonfly, recorded at 6,200 m in the Himalayas. It was also first dragonfly species that settled on Bikini Atoll after the nuclear tests there.[13] Furthermore, it is the only Odonata on Easter Island. These individuals seem to be a small gene pool, derived from the continental populations, which is slowly creating a new type by genetic drift. In colder areas like South Australia and Northern Canada, the species cannot overwinter and must therefore be replaced by new migrants each year.[5]
