A FEW NOTES ON BIRDS FROM PERAK, MALAY 



PENINSULA. 



By ERNST HAETEET and A. h. BTJTLER. 



BOTH authors of this article have been fortunate enough to collect on Gunong 

 Ijau, a mountain of about 4300 feet, the highest of the Lanit HUls, close to 

 Taiping, in the State of Perak, Malay Peninsula, Hartert in 1888, Butler in 1898. 

 Hartert devoted most of his time on Gnnong Ijau to entomological collecting, but 

 a list of the birds collected by him, with field-notes and descriptions of eggs and 

 nests, is given in the Journal fiir Ornithologie, 1S80, ])j>. 379 — 406. A fnll list 

 of the birds collected and observed by Butler will be published, together with 

 tield-notes, in the Journal of the Bombaij Saiiirul Ilislori/ Societi/. Here we are 

 only giving a few systematical notes, principally on new species and subspecies 

 found by Butler. 



The ornithology of Perak is known to a certain extent. Kelham made a large 

 collection of birds in the low country, and gave a list and most useful notes in the 

 Ibis for 1881; but, excellent as his observations are, he never ascended the mountains, 

 and consequently did not discover any new sj)ecies. The next collector was 

 L. Wray, Curator of the Perak Museum. His discoveries in the mountains were 

 rather startling. They are published in the Proceedings of the Zoological Society of 

 London for lsS(J, 1887, 18s8. Then follows Hartert's list in 1889. That the higher 

 elevations of the Malay Peninsula are yet a good lielil for an ornithologist is clearly 

 manifested by Butler's discoveries. Gnnong Ijau is the best-known of the Perak 

 mountains, bnt it is also one of the best collecting grounds one can imagine, being, as 

 its name (Gnnong Ijau = Green Mountain) indicates, covered with dense forest from 

 bottom to top, with the exeejrtion of a few recent clearings. On the other hand, 

 this same luxurious vegetation and the steej)ness of the monntain-sides, with their 

 many ravines and blocks and fissures, make progress very difficult, and many 

 a specimen is lost to sight when shot, and never retrieved. 



The following are the species which call forth some systematical notes :—

t? ? shot on Gunong Ijau. The Perak si)ecimens collected by both Hartert 

 and Butler differ from typical /. tickelli from Tenasserim in having the irown of 

 the head darker and less rufous, the ear-coverts more dingy grey, the breast and 

 flanks slightly more ashy. (See Hartert's notes in J./. 0. 1889, j). 38«.)
