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/Pantala_flavescens

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]

PaudurHill (Nepal) Raptor Migration Update 28Sept – Day 13

Yellow-throated Martin

Dragonfly migrating in our watchsite; help for identification is welcome

Weather is gradually improving in this part of country. Mostly going to be sunny in the watch site however the Himalayan peaks can’t be seen in the afternoon due to thick cloud cover.  The mountain slopes were so hazy today and very difficult to identify the distant birds. We are getting continuous migration of Black kites, Oriental Honey Buzzard, Common Buzzard, Eurasian Hobby, Common Kestrels, Peregrine, Booted Eagle and other species which were seen before. Last two days are going to be exciting for Barn Swallows, Red-rumped Shallows and Dragonflies migration. We had more than 800 shallows and more than 400 Dragonflies for 27 and 28 Sept. All of these migrants will be continuous in the coming week.  I have no idea on dragonfly identification, help from anybody is welcome. Flocks of resident vulture are also seen from today. Today we had Himalayan vulture as a new arrivals. Wow pretty huge bird – about 12kg (26 pounds).  
Today we also had three Yellow-throated Martins very close to the lookout. They were climbing over the roof of restaurant and one went inside from the small hole. The restaurant is still closed, I am not sure when they will open.

PaudurHill (Nepal) Raptor Migration Update 26Sept – Day 11

Eurasian Hobby

Weather is improving in last days. From yesterday we have hot shower in the centre. Weather was far better in 25th and mostly the sky was clear overhead however it was mostly cloudy over Annapurna Himalaya after 10:00. The wind was peaking up after 10:00 and reached the average speed of 7.5 km/hr. The migration was exciting in terms of species we are getting in the last two days. The highest numbers of migrants were Black Kites. Five new species of raptors (Booted Eagle, Indian Vulture, Short –toed Eagle, Long-legged Buzzard and Common Buzzard) were arrived in our watch site. Today morning was busy for small birds. Mostly Red-rumped Swallows were peaking before 8:00.  Over 100 Red-rumped were counted between 7:30 to 8:00. Numbers of Dragonflies are also increasing. Passerine migrants were Barn shallows, Red-rumped swallows and House swifts.
