Vesper Sparrow and Other Bird Songs, livre audio

Vesper Sparrow can be found in both open spaces and bushy woodland. The male sings from a higher perch, such as a shrub or fencepost. The musical song begins with two pairs of repeated whistled notes and ends in a series of trills. In summer, its clear song may be heard at any time of day but it sings most impressively in the evening. This recording offers continuous Vesper Sparrow birdsong recorded in its natural habitat of grasslands together with other birds and ground creatures.
