PASSER EUCHLORUS. 259 



numbers at the town of Khartoum, perching on the walls and 

 roofs of the houses, and iu September and October they 

 resorted to the open country in thousands with their young. 

 The nest is of an oval form, deeper than wide, composed of fine 

 dried grass and firmly fixed to a bough from two to twelve feet 

 from the ground. They lay three to four eggs, which are 

 white spotted with brown, very similar in colouring to those of 

 our common House-Sparrow, and measure 0*7o x 0'55. 



The Hon. N. C. Rothschild and Mr. A. F. R. Wollaston 

 found these beautiful yellow Sparrows exceedingly abundant at 

 Shendi, increasins' in number towards the end of March. 

 " Flocks of fifty and upwards might be seen at any time flying 

 northwards along the river-bank ; they were never seen to 

 proceed in the other direction. They are very partial to water, 

 and might sometimes be seen in enormous flocks bathing in the 

 shallow pools of the river." 



On the White Nile, according to Mr. Witherby, "This 

 species was common and well distributed. Grenerally to be 

 found in small flocks of twenty or so, it was very wild, and 

 frequented the bushes and trees in the more open country. 

 When flying it has a twittering Linnet-like note, while in the 

 trees it chirps like a House-Sparrow. We saw an enormous 

 flock of these birds in some tall bushes on the river-bank near 

 Kawa. They were exceedingly restless, rising in clouds from 

 the bushes as we approached and settling again further on, 

 only to rise when we neared them."
