Just had a very bizarre, but great experience in my office toilet!
The urinals look out of over the roof tops of the nearby office buildings, and whilst standing there I picked up three large birds on a distant thermal. Thinking they would be feral Painted Storks, but worth a check, I decided to return to my desk and grab my carry-everywhere compact binos, running the risk of being found in the lavs with my binoculars and trying to explain that away! On my return to the bathroom I couldn't see the three birds in the distance, so looked directly up to see if they were circling overhead...to my astonishment I found a flock of approximately 30 SPOT-BILLED PELICANS (a near-threatened species) circling directly over my office!
I ran outside and found them still circling, and gaining height, then they headed SW towards Rama 6 Road, where Phil Round's office is - I made a quick call to him when I got back to my desk but the flock must have already passed over. Phil mentioned that he sees a few feral birds around the city, but that a flock of this size would be wild birds.
Whilst watching the pelicans I also had 3 drongo spp pass over in the same direction. Gotta love vizmig!
