• Spizella pusilla
• Length: 4.7-5.9 in (12-15 cm)
• Weight: 0.4-0.5 oz (11-15 g)
• Wingspan: 7.9 in (20 cm)

Field Sparrows remain all year in eastern US states, but those that breed in the Midwest head south for winter.

You can easily find Field Sparrows in the breeding season as the males will sing from a perch in the early mornings, so they are easier to spot. Otherwise, they quietly feed on weeds and seeds and can be easily missed as they prefer abandoned fields and are shy.

Nests of Field Sparrows are built on the ground for the first brood and then higher and higher as the breeding season goes on. Their nests are made from grass, and they lay up to five eggs which take around two weeks to hatch. After that, the young only take around a week to fledge.

Attract Field Sparrows to your backyard with cracked corn, hulled sunflower seeds, and millet.

28. Eastern Phoebe

Eastern Phoebes are not often spotted in Wyoming but there have been occasional sightings in the state during summer.

Eastern Phoebes are plump songbirds that are grayish-brown on the back, whitish underneath, and with a darker head.

• Sayornis phoebe
• Length: 5.5-6.7 in (14-17 cm)
• Weight: 0.6-0.7 oz (16-21 g)
• Wingspan: 10.2-11.0 in (26-28 cm)

Eastern Phoebes are migratory birds, breeding across northeastern and central US states and into Canada before migrating to southeastern US states and Mexico for winter. Some birds may remain all year towards the south of their range. 

Eastern Phoebes tend to be found alone in quiet woodland, wagging their tails from low perches rather than in pairs or flocks. 

As they are flycatchers, flying insects make up most of their diet, but they will also eat spiders and other insects, small fruit, and seeds. They often nest on bridges, barns, or houses, making a nest out of mud and grass.

Attract Eastern Phoebes to your backyard by putting up a nest box or native plants that produce berries.

29. Purple Finch – Female

Purple Finches are not often spotted in Wyoming but they have been occasionally spotted here during winter.

Female Purple Finches are brown-streaked all over, but males have reddish-purple heads and breasts with more brown on the back and wings and have a paler belly. They look very similar to House Finch but are redder, especially at the top of their back. 

• Haemorhous purpureus
• Length: 4.7-6.3 in (12-16 cm)
• Weight: 0.6-1.1 oz (18-32 g)
• Wingspan: 8.7-10.2 in (22-26 cm)

Purple Finches breed in Canada and overwinter in eastern US states but can be found all year in the north-east and Pacific coast.

You can find Purple Finch in evergreen forests feeding on seeds but also buds, nectar, and berries.

Nests of Purple Finches are located high up in trees. They are made of twigs, barks, weeds, and moss. They usually hold three to five eggs that are incubated for thirteen days by the female.

Attract Purple Finches to your backyard with black oil sunflower seeds.
