The common Indigo Bird of the Eastern States is found in nearly uniform and tolerable abundance in various parts of the United States, from the valley of the Missouri to the Atlantic, and from Florida to New Brunswick. It is a summer visitant, but rare, in Eastern Maine, but is common in the western part of the State, where it arrives early in May, and where it breeds. Mr. Allen speaks of it as not very common in the vicinity of Springfield, Mass., arriving there about the middle of May, and breeding in gardens, orchards, and the edges of woods, and making its nests in bushes. It leaves there about the middle of September. In the eastern part of the State it is very unequally distributed. In certain localities it has not been met with, but in other favorite places it seems to be quite common, and to be on the increase. In the gardens of Brookline and Roxbury they are comparatively quite abundant. Mr. Maynard gives May 10 as the earliest date of their coming. He also states that in the autumn they are found in flocks, and frequent roadsides, high sandy fields, and rocky pastures, which I have never noticed. According to Dr. Coues, it is common and breeds as far south as Columbia, S. C., and, according to Mr. McIlwraith, it is a common summer resident in the neighborhood of Hamilton, Canada West. Specimens have been procured as far west as Fort Riley in Kansas. It passes the winter in Guatemala, where it is quite abundant, though a very large proportion of specimens received from there, in collections, are immature birds. It was not found in Vera Cruz by Mr. Sumichrast, nor is it given by Mr. Allen as found by him in Western Iowa, while it was common both in Northern Illinois and in Indiana. It was, however, found by Mr. Allen, in Kansas, in considerable numbers, near Leavenworth, in the spring of 1871. It was not met with by Mr. Dresser in Southwestern Texas, though Dr. Woodhouse found it quite common in the prairies of that State, where its pleasant song was heard in the timber on their edges, or in the thickets on the borders of the streams in the Indian Territory, where it was quite abundant. It was not observed on the Mexican Boundary Survey. These birds were found, by Mr. Boucard, abundant throughout the State of Oaxaca, Mexico, having been taken both among the mountains near Totontepec, and among the hot lowlands near Plaza Vicente.
