Well, thought I'd let you know how it went:
Generally, I had little time as this was a business trip. We were checking out a number of resorts but I did see some pretty good birds.
After arriving very late the previous night, immigration was a nightmare, I struggled out of bed and onto the very nice veranda of the Ulma Ubud where we were staying. The place was heaving with Spotted Doves and Yellow-vented Bulbuls, surely the most common species by far on Bali. The trees were also full of what looked like Plantain Squirrels(?), whilst overhead were plenty of Cave Swiftlets. Whilst not a lifer, good views of Chestnut-breasted Malkoha were nice whilst the ubiquitous Olive-backed Sunbirds and Common Ioras were well known from my home turf.
Right at the entrance to the first resort we visited were a flock of my first endemic lifer, Javan Munias. These are much smarter looking than the local Munias and appeared to be very common, but even the Scaly-breasted Munias looked smarter than they do here in Vietnam.
Lunch was at an organic restaurant in the middle of some rice paddies (called the Sari Organic, this restaurant alone would make me consider returning to Bali), a lengthy Siesta produced both Zitting and Bright-headed Cisticolas as well as Javan Pond Heron.
Visiting another resort in the afternoon, my colleagues went for Spa treatments whilst I went for a walk. Good thing, too as it produced the first bird on my personal wish list, a Javan Kingfisher. This bird is amazingly beautiful and would also be the only one seen on the trip. I also saw a Needletail but views were to short to clinch it 100%.
The next day had nothing new at all, but a visit early on the last morning to Ulu Watu was very profitable indeed. I was very apprehensive about the Macaques but they did not even deem me fit to look at, much to my relief.
The first bird heard, but not seen, was a Drongo Cuckoo. A very restless bird turned out to be another lifer, a Bar-winged Prinia, followed shortly by another addition to my list, an Olive-backed Tailorbird.
I failed to locate a bird I really wanted to see, Tropicbird, but a couple of Brown Boobies almost made up for that. My only Mynas of the trip were a pair of Javan Mynas. Here I also saw the only Woodpecker of the trip, a Fulvous-breasted Woodpecker. Three Collared Kingfishers were eying the ever-present Macaques and as I was leaving, I spotted a single Pink-necked Green Pigeon and finished the excursion with another lifer, a Green Junglefowl.
All in all a pretty good trip and I do hope to go back one day.
