The present species has commonly been called Sterna melanogaster 

 Temminck, 1827, with reference to the Nouveau recueil de planches 

 coloriees d'oiseaux, vol. 5, livr. 72, 1827, pi. 434. Temminck's name, 

 however, cannot be used inasmuch as Horsfield (Zoological researches 

 in Java, No. 8, 1824, general catalog) has used Sterna melanogaster 

 "T[emminck]" as a substitute name for Sterna Javanica Horsfield 

 1821, which= Ohlidonias hybrida javanica (Horsfield). 



STERNA ALBIFRONS SINENSIS Gmelin 



Chinese White-fronted Tern 



[Sternal sinensis Gmklin, Systema naturae, vol. 1, pt. 2, 1789, p. 608 (China, ex 

 Latham). 



The only record for our area is based upon a specimen in the Royal 

 Natural History Museum in Stockholm, taken by Eisenhofer and with 

 no data other than "Norcl Siam." If we assume that the locality is 

 correct, this bird probably came from either the system of the Mae 

 Yom or that of the Mae Wang. Since the species has been found not 

 only along the coasts of Thailand but also on the Chao Phraya river, 

 it is not at all unlikely that it should sometimes occur along the larger 

 streams of our provinces. 



A breeding male from southeastern Thailand had the bill yellow 

 with black tip ; the tongue and interior of the mouth yellow ; the feet 

 and toes yellow. 



In nuptial dress this tern has the forehead white, this color extending 

 back over the eye at the sides ; the lores and the rest of the crown and 

 nape black ; the remaining upperparts silvery gray, becoming almost 

 white on the upper tail coverts and tail; the underparts white. Its 

 nonbreeding plumage is similar to that of other species. 



This is much the smallest of our terns. The tail is relatively short 

 but is deeply forked.
