LITTLE CRESTED GREY; TYRANT . 169 
slender in form, with a long tail, its total length being 
six inches. The sexes are alike in colour ; the upper 
parts are yellowish grey, breast and belly light yellow. 
They are found living in pairs, all the year round, 
in thorn bushes, and are scarcely ever seen to rest, 
but hop incessantly from twig to twig, in a delicate 
leisurely manner, seeking on the leaves for the 
minute caterpillars and other insects on which they 
live. While thus engaged they utter a variety of 
little chirping and twittering notes, as if conversing 
together, and occasionally the two birds unite their 
voices in a shrill impetuous song.
