1994年10月至1995年6月，在老挝的六个主要地区进行了鸟类调查，在许多其他地点进行了偶然的观察，直到1995年8月。大部分工作是在北纬17°26'和18°40'之间的四个地点（Nakay高原，Phou Khaokhoay国家生物多样性保护区（NBCA），Nam Kading NBCA和附近的三个石灰岩露头），但在南部的Bolaven高原进行了大量工作，并对最北部的Phou Dendin NBCA进行了短暂访问。后者是自1950年以来对万象北部一个地点的首次鸟类调查。收集了15种全球濒危物种和28种全球近危物种的信息（Sensu Collar等人，1994年），老挝有9种处于危险之中，7种可能处于危险之中，1种在老挝的威胁鲜为人知（Sensu Thewlis等人，编写中）。另一个全球近危物种被暂时记录。灰边鸫和黑头鹀的记录是印度支那的第一次。红麻鸭Tadorna ftrrugalus、小杜鹃Cuculus poliocephalus、斑嘴鸥Larus ichthyaetus（1995年12月）、Dunlin Calidris alpina、长趾Stint C subminuta和栗腹Sitta nagaensis为老挝新记录，欧亚黑鸟Turdus merula为柬埔寨新记录。在老挝北部、中部和南部分别发现了12种（加上一种临时确定的）、9种和5种（加上一种临时确定的）新物种。大多数讨论涉及地理分布，但也包括发生的季节性和海拔范围。
Between October 1994 and June 1995 birds were surveyed at six main areas in Laos, with incidental observations at many other sites extending until August 1995. Most effort was at four sites between 17°26' Nand 18°40' N (the Nakay Plateau, Phou Khaokhoay National Biodiversity Conservation Area (NBCA), Nam Kading NBCA and three nearby limestone outcrops), but there was extensive work on the Bolaven Plateau to the south and a brief visit to Phou Dendin NBCA in the extreme north. The latter is the first bird survey of a site much north of Vientiane since 1950. Information was collected for 15 Globally Threatened species and 28 Globally NearThreatened species (sensu Collar et al. 1994), nine species At Risk in Laos, seven potentially so and one where threats in Laos are little known (sensu Thewlis et aL in prep.). A further Globally Near-Threatened species was recorded provisionally. Records of Grey-sided Thrush Turdus ftae and Black-headed Bunting Emberiza melanocephala were the first for Indochina. Ruddy Shelduck Tadorna ftrruginea, Lesser Cuckoo Cuculus poliocephalus,Pallas's Gull Larus ichthyaetus (from December 1995), Dunlin Calidris alpina, Long-toed Stint C subminutaand Chestnut-vented Nuthatch Sitta nagaensiswere new to Laos and Eurasian Blackbird Turdus merula to Cambodia. A total of 12 (plus one provisionally identified), nine and five (plus one provisionally identified) species were found new for North, Central and South Laos respectively. Most discussion concerns geographical distribution, but seasonality of occurrence and altitudinal ranges are also covered.
