There is a growing recognition of the need to integrate non-trophic interactions into ecological networks for a better understanding of whole-community organization. To achieve this, the first step is to build networks of individual non- trophic interactions. In this study, we analyzed a network of interdependencies among bird species that participated in heterospecific foraging associations (flocks) in an evergreen forest site in the Western Ghats, India. We found the flock network to contain a small core of highly important species that other species are strongly dependent on, a pattern seen in many other biological networks. Further, we found that structural importance of species in the network was strongly correlated to functional importance of species at the individual flock level. Finally, comparisons with flock networks from other Asian forests showed that the same taxonomic groups were important in general, suggesting that species importance was an intrinsic trait and not dependent on local ecological conditions. Hence, given a list of species in an area, it may be possible to predict which ones are likely to be important. -
Species Limits in Some Philippine Birds Including the Greater Flameback Chrysocolaptes Lucidus
FORKTAIL 27 (2011): 29–38 Species limits in some Philippine birds including the Greater Flameback Chrysocolaptes lucidus N. J. COLLAR Philippine bird taxonomy is relatively conservative and in need of re-examination. A number of well-marked subspecies were selected and subjected to a simple system of scoring (Tobias et al. 2010 Ibis 152: 724–746) that grades morphological and vocal differences between allopatric taxa (exceptional character 4, major 3, medium 2, minor 1; minimum score 7 for species status). This results in the recognition or confirmation of species status for (inverted commas where a new English name is proposed) ‘Philippine Collared Dove’ Streptopelia (bitorquatus) dusumieri, ‘Philippine Green Pigeon’ Treron (pompadora) axillaris and ‘Buru Green Pigeon’ T.

Vietnam Southern and Central Specialties 15th to 29th February 2020 (15 days) Trip Report Siamese Fireback by Simon Tan Trip report compiled by Tour Leader: Glen Valentine Trip Report – RBL Vietnam – Southern & Central Specialties 2020 2 Tour Summary Orange-breasted Trogon by Simon Tan We kicked off our 2020 Southern and Central Vietnam tour in the city of Hue, teeming with history and cultural significance and some wonderful restaurants, making it the perfect place to spend a few pre-tour days ambling around the city and its surrounds. Beginning our long journey south towards the hill forests surrounding the village of Mang Den, our first scheduled birding stop of the day produced the wanted target species in the form of White-faced Plover (a very distinctive, extremely localized, rare and often- split subspecies of Kentish Plover) along the beach adjacent to Bach Ma National Park. In the same area, we added our first of several Light-vented Bulbuls, a female Stejneger’s Stonechat and flocks of fly-over Grey-capped Greenfinches. Continuing west and then southwards, crossing over the Lo Xo Pass after a quick lunch-stop we had an hour or so to find the scarce and exceedingly range-restricted near-endemic Black-crowned Barwing. This good-looking and charismatic species was only discovered as recently as 1996 and is still only known from a tiny area in south-central Vietnam and southern Laos. We arrived in fine weather and were soon admiring several pairs and family groups of Black-collared Starling, as well as Scarlet Minivet, Streaked Spiderhunter, Black Bulbul, a wonderful perched Necklaced Barbet, a pair of Large Woodshrike and then finally, after a fair amount of searching in the now-degraded road- edge habitat, a glorious pair of Black-crowned Necklaced Barbet by Glen Valentine Rockjumper Birding Tours View more tours to Vietnam Trip Report – RBL Vietnam – Southern & Central Specialties 2020 3 Barwings. -

Stokke1,2, Longwu Wang3, Canchao Yang4, Aiwu Jiang5, Wei Liang4, Eivin Røskaft1 and Frode Fossøy1,2* Abstract Background: Our knowledge of avian brood parasitism is primarily based on studies of a few selected species. Recently, researchers have targeted a wider range of host–parasite systems, which has allowed further evaluation of hypotheses derived from well-known study systems but also disclosed adaptations that were previously unknown. Here we present developmental and behavioral data on the previously undescribed Plaintive Cuckoo (Cacomantis merulinus) nestling and one of its hosts, the Common Tailorbird (Orthotomus sutorius). Methods: We discovered more than 80 Common Tailorbird nests within an area of 25 km2, and we recorded nestling characteristics, body mass, tarsus length and begging display every 3 days for both species. Results: Plaintive Cuckoo nestlings followed a developmental pathway that was relatively similar to that of their well-studied relative, the Common Cuckoo (Cuculus canorus). Tailorbird foster siblings were evicted from the nest rim. The cuckoo nestlings gained weight faster than host nestlings, and required 3–9 days longer time to fedge than host nestlings. Predation was high during the early stages of development, but the nestlings acquired a warning display around 11 days in the nest, after which none of the studied cuckoo nestlings were depredated. The cuckoos’ begging display, which appeared more intense than that of host nestlings, was initially vocally similar with that of the host nestlings but began to diverge from the host sound output after day 9. -

Nesting of Green-Billed Coucals Centropus Chlororhynchos in Sinharaja, Sri Lanka
FORKTAIL 15 (1999): 43-45 Nesting of Green-billed Coucals Centropus chlororhynchos in Sinharaja, Sri Lanka MARTIN WIJESINGHE [Translated from a Sinhala manuscript by Gehan de Silva Wijeyeratne] An account of the discovery of a nest of Green-billed Coucals Centropus chlororhynchos is presented with some observations made during the nesting period. Observations indicate that bill colour varies from ivory during breeding to pale green in the post-breeding state. Nests observed were in the tree Wendlandia bicuspidata (family Rubiaceae), leading to speculation that the coucals may have a preference for nesting in this tree. The Green-billed Coucal Centropus chlororhynchos (see daily. The nest-building was repeated over the next few note 1), endemic to Sri Lanka, is slightly smaller than days. However, from 12 October onwards I failed to see the Greater Coucal Centropus sinensis parroti, a familiar the birds there. Nonetheless, as I could hear them calling bird of garden and field. Its bill is slightly larger than in the distance, I suspected they may be nest-building that of the Greater Coucal and has a greenish tinge (see in the area and searched an area of about 20 acres note 2). The male is slightly larger than the female, but without success. I persisted, and on 28 October, on otherwise the sexes are similar. The black feathers on hearing the birds calling at the earlier site, I hastened the head and neck have a purple iridescence but often across. I discovered the birds constructing a new nest the head looks glossy black. The wings are chestnut. -
Passeriformes: Cisticolidae: Orthotomus) from the Mekong Floodplain of Cambodia
FORKTAIL 29 (2013): 1–14 http://zoobank.org/urn:lsid:zoobank.org:pub:F1778491-B6EE-4225-95B2-2843B32CBA08 A new species of lowland tailorbird (Passeriformes: Cisticolidae: Orthotomus) from the Mekong floodplain of Cambodia S. P. MAHOOD, A. J. I. JOHN, J. C. EAMES, C. H. OLIVEROS, R. G. MOYLE, HONG CHAMNAN, C. M. POOLE, H. NIELSEN & F. H. SHELDON Based on distinctive morphological and vocal characters we describe a new species of lowland tailorbird Orthotomus from dense humid lowland scrub in the floodplain of the Mekong, Tonle Sap and Bassac rivers of Cambodia. Genetic data place it in the O. atrogularis–O. ruficeps–O. sepium clade. All data suggest that the new species is most closely related to O. atrogularis, from which genetic differences are apparently of a level usually associated with subspecies. However the two taxa behave as biological species, existing locally in sympatry and even exceptionally in syntopy, without apparent hybridisation. The species is known so far from a small area within which its habitat is declining in area and quality. However, although birds are found in a number of small habitat fragments (including within the city limits of Phnom Penh), most individuals probably occupy one large contiguous area of habitat in the Tonle Sap floodplain. We therefore recommend it is classified as Near Threatened on the IUCN Red List. The new species is abundant in suitable habitat within its small range. Further work is required to understand more clearly the distribution and ecology of this species and in particular its evolutionary relationship with O. atrogularis.

All photos in this report were taken by Sam Woods. 1 www.tropicalbirding.com +1-409-515-0514 [email protected] Page Tropical Birding Trip Report Sri Lanka: January 2015 INTRODUCTION In many ways Sri Lanka covers it all; for the serious birder, even those with experience from elsewhere in the Indian subcontinent, it offers up a healthy batch of at least 32 endemic bird species (this list continues to grow, though, so could increase further yet); for those without any previous experience of the subcontinent it offers these but, being an island of limited diversity, not the overwhelming numbers of birds, which can be intimidating for the first timer; and for those with a natural history slant that extends beyond the avian, there is plentiful other wildlife besides, to keep all happy, such as endemic monkeys, strange reptiles only found on this teardrop-shaped island, and a bounty of butterflies, which feature day-in, day-out. It should also be made clear that while it appears like a chunk of India which has dropped of the main subcontinent, to frame it, as merely an extension of India, would be a grave injustice, as Sri Lanka feels, looks, and even tastes very different. There are some cultural quirks that make India itself, sometimes challenging to visit for the westerner. -

(Orthotomus Sutorius) Parasitism by Plaintive Cuckoo
Nahid et al. Avian Res (2016) 7:14 DOI 10.1186/s40657-016-0049-y Avian Research SHORT REPORT Open Access First record of Common Tailorbird (Orthotomus sutorius) parasitism by Plaintive Cuckoo (Cacomantis merulinus) in Bangladesh Mominul Islam Nahid1,2, Frode Fossøy1, Sajeda Begum2, Eivin Røskaft1 and Bård G. Stokke1* Abstract The Plaintive Cuckoo (Cacomantis merulinus) is a widespread brood parasite in Asia, but no data on host species utili- zation in Bangladesh exist. By searching for nests of all possible host species of the Plaintive Cuckoo at Jahangirnagar university campus, north of Dhaka, we were able to determine which hosts were used in this area. We found that the Common Tailorbird (Orthotomus sutorius) was the only potential host used by Plaintive Cuckoos, and parasitism rate was rather high (31.3 %, n 16). However, both host and cuckoo breeding success was poor (0 %, n 16) due to fre- quent nest predation. Details= on host and cuckoo egg appearance are provided. Our findings indicate= that Common Tailorbirds are common hosts of the Plaintive Cuckoo in Central Bangladesh.
