The seventh week of Michael W. Potter's Birds of the Bow Valley series features the common yellowthroat – a species of warbler – and small colourful birds known for their bubbly songs.
The two photos have a male on the left, with a black mask, and a female on the right. They both have food being taken to young birds. The photos were taken in the Cave and Basin area of Banff National Park in July, but four years apart, showing the habitat is good breeding territory.
