The behavior Shorebirds on mudflat in along Celebes coast
The penetrability of a beach sediment depends on its water content. This may be reason that some shorebirds can be seen running along the water’s edge on the ebbing tide pushing their bills into the thixotropic (fluid) sand. A careful examination of bill marks made in tidally formed sand ripples by dowitchers, a wading bird similar to godwits, showed that more marks were found on the crests than in the water-logged troughs.
Neither the distribution of prey nor sediment grain size showed only difference between crests and troughs, but penetrating the crests required only 50%-70% of the force required to penetrate the troughs. Thus, concentrating effort on the crests reduce energy expenditure. Ripple crests are sites of active sediment transport and the arrangement of the grains is relatively unstable. This larger volume of pore space allows a higher water content and offers less resistence to penetration. Although the differences in water content between crest and trough are small, minor differences in pore volume can produce major changes in the reaction of sand grains to a shearing force (Grant 1984).
Wading birds are often seen in mixed-species flocks which might be thought to be disadvantageous to the individuals by virtue of increased competition. In fact, more often than not, the birds are taking different foods and being together has the advantage that the more birds present the more likely it is that a predator, such as a bird of prey, will be seen. One particular species is usually first to settle on a certain stretch of beach having used visual clues to make its choice. Other species follow when it is clear that food is being found. A few species act as pirates taking food have to spend more time feeding to compensate for the loss, but here are advantages in that feeding birds have their heads down searching for food whereas the pirates generally keeps its head up and serves an early warning of the approach of predators (Barnard and Thompson 1985).

Trekking until Birding Bali Mountain
Up into the hills
Now it is time to head for our first night’s destination, Bedugul in the central highlands- a mere 1 to ½ hour’s drive. An alternative more leisurely option is to make a whole day of the next stage of the journey with a detour via the amazing jungle temple, Pura Luhur, on the southern slopes of Mt Batukau. This will take you through the most spectacular landscape on the island-weather permitting.
Taking the Jl. Ngurah Rai bypass road, go straight across the crossroads in Tohpati and come out north of Denpasar on the road to Tabanan. In Tabanan pay heed to the one-way system, taking a right turn after the market and doubling back so as to reach the road leading north to Penebel. Half way to Penebel, take a left turn to Yehpanas (hot springs), continuing north to the Pura Luhur. At Tengkudak pause briefly to visit astonishing church- a brick, syncretic folly elaborated with Balinese sculpted angels and demons-before proceeding to Wangagadege (Wangaye for short), where the jungle begins. The road climbs more steeply now, and it is worth stopping to examine one or more of the vast, wayside fig trees for imperial and green pigeons, fruit-doves, minivets and barbets. The distribution of the latter in Bali, their last oriental outpost, is strange: here, in central Bali, orange-fronted, blue eared and coppersmith Barbets can be seen together in the same tree.
Some doubtless well-intentioned “improvements” to the temple precints have recently been made and the old rustic spirit of the sanctuary has to some extent now been lost. Even the lake has been cleaned up. But no matter, there are still birds in abundance. Mugimaki, little Pied and Grey-headed Flycatchers, Black-naped Monarchs, Whiterumped Warblers, Black-winged Hemipus, and orange-bellied and Blood-breasted Flowerpeckers will all be found here. You are almost bound to see the striking, pied White-crowned Forktail. Look for it in the feeder streams to the shrines and pond or, failing there, in the tumbling river-bed, which nay be gained by taking the forest path on the left before the temple.
After a bathe in the river, which is icy and so clean that you can drink from it, it is time to return to Wangaye, from where you turn left on to the pot-holed road to Jatiluwih. Drive slowly along this road, not because it is bad, but so as not to miss the wonderful landscape. There are various contenders for the most scenic route in Bali, but this one surely takes the prize. Pied Bushchats and Javan Kingfishers are everywhere-and keep an eye to the heavens for Black Eagle. Break the journey at Jatiluwih (the name means “lovely view”) and over a picnic lunch gaze in awe at the unfolding panorama of rolling rice terraces…and go on gazing. And on at length to the hamlet which is listingly Senganan Kanginan, then left on a slightly better road which joins the main road to Bedugul at Pacung.
If you do not take a packed lunch, the restaurant Mutiara Sari in Baturiti has a fine bill of fare and, amazingly, fresh milk from the local dairy herd. If it is a nice day, sit out in the ornamental garden; the view here also grand. What is that peculiar liquid twitter, followed by a shushing sound? Here are the first Brown Honeyeaters of the tour.
