Among the most common summer birds in the country, the Red-eyed Vireo is abundant throughout Canada's eastern forests, where it forages for insects and occasionally fruit. A highly vocal species, males are known for long singing bouts with complex, individual songs that can include mimicry of other species.

Red-eyed Vireo
In Canada, the Red-eyed Vireo inhabits deciduous and mixed forests from British Columbia to Newfoundland. It winters in the Amazon Basin in South America. There are approximately 82 million individuals in Canada, which represents 63% of the global population and a high degree of responsibility for Canada. The Canadian population of Red-eyed Vireo has shown a moderate increase relative to 1970. Confidence in this assessment is high because the Breeding Bird Survey provides good coverage of the breeding range and has high precision in its trend. The national population of Red-eyed Vireo is within its goal range.
The best source of information on the population status of Red-eyed Vireo is the Breeding Bird Survey (BBS). Although the northernmost limits of its range are poorly sampled, most of the range is covered well by the BBS, and precision of estimates is high, allowing for high reliability overall. The national BBS data show a moderate long-term increase in abundance since the early 1970s, with several pulses of growth around the mid-1970s, mid-1980s, mid-1990s, and since 2012. The increases have been observed throughout most of the Canadian breeding range, but there has been little change in the southern Prairies, and declines through most of British Columbia.
The goal for Red-eyed Vireo is to remain at or above its recent population level, based on the Breeding Bird Survey. Trend data show that Red-eyed Vireo is currently within its goal range.

Among the most common summer birds in the country, the Red-eyed Vireo is abundant throughout Canada's eastern forests, where it forages for insects and occasionally fruit. A highly vocal species, males are known for long singing bouts with complex, individual songs that can include mimicry of other species.
Red-eyed Vireo is primarily reported between May and October in Canada, as it migrates south in the nonbreeding season.
