month of April, and wears off again almost to a band on 

 the breast in July. The upper surface is also darker in 

 April, including the black at the base of the tail and the 

 ends of the primaries. 



Three eggs, collected on October 16, 1903, are pinky 

 white to rich cream-coloured with large sepia-brown blotches, 

 mostly at the larger end, and underlying spots of lavender- 

 grey. Axis r05-l*15 inch ; diam. 085. 



[This species is resident, but not common, in Paraguay. 

 As it is a camp-loving bird and is usually perched upon some 

 conspicuous post or dead tree its presence is easily detected, 

 and its white-barred wings serve to identify it when in flight. 

 During the breeding-season individuals are to be met with in 

 pairs, but the rest of the year they are solitary. Although 

 they undoubtedly nest here, I know nothing of their 

 breeding-habits. — TV. F.~]

[This is one of our rare Paraguayan birds and is only to 

 be met with in swampy districts which border on the forest. 

 A lonely tree of low grow r th is the most favourite perch of 

 this bird, the white plumage making it visible at a consider- 

 able distance. It is generally safe from the hunter, as the 

 impassable swamps in which it lives are wisely avoided. The 

 only time when it is possible to shoot it is in the early 

 morning, when it first leaves the shelter of the forest and 

 being hungry is somewhat more careless than during the rest 

 of the day.— JV. F.]
