Though unable to give precise data, judging from the series of specimens in the 
British Museum, J. plumbea is possibly a resident throughout the greater part of 
South America. Natterer obtained twenty-five examples in Brazil, but only between 
September and January, which leads one to suppose that it is a winter visitant in 
that country. ‘There are none but adult examples from Guiana, Amazonia, Bolivia, 
and Brazil in the Museum; however, young birds occur in collections from Colombia 
and Ecuador, and there is a nestling from Calobre'* in Panama. The Nicaraguan 
specimens in our collection were obtained by Mr. Richardson in March and April, 
others were procured from Guatemala in April, July, and November, and near Lanquin 
we saw one building in a pine-tree, patches of which are to be found in many parts 
of Alta Vera Paz? ?°, 
Mr. Richardson procured examples at Tampico in June and from San Luis Potosi 
in July, so the species doubtless breeds in these provinces. Sumichrast 18, however, 
states that in Tehuantepec it is only a bird of passage, as also on the coast of Vera 
Cruz; at San Andres Tuxtla he saw several flocks travelling northwards, but these 
may have been the allied species J. méssissip piensis. 
In Yucatan J. plumbea is not a common bird, and Gaumer obtained but one specimen 
at Tizimin at the end of March.
