One week ago, nice encounter with 3 Short-eared Owls. As I was checking the most suitable site for this species around Hanoi - some dozens of kilometers away from the city -, I flushed an individual at about 4pm, at very short distance (6-7 meters). Twenty meters more on the right or 20 meters more on the left, and I am pretty sure that the owl wouldn't have moved a single talon! Fifteen minutes later I flushed 2 other guys as I was chasing the first one, again at very close distance. Two hours before, I had already crossed this place but saw nothing... except Paddyfield Pipits!
Very easy to overlook a bird like this... especially for a mid-day birder like me ;)
I didn't see any of them hunting, but I presume they are active at dusk and dawn.
The site : large sandy area along the Red River (500m away on the horizon), seasonnally flooded, with sparse vegetation.
