- Loose feathers that detach to evade predators.
The Mourning Dove’s mournful coo adds a haunting soundtrack to its widespread presence.
Eurasian Collared-Dove

Although native to warm temperate and subtropical regions of Asia, Europe, and northern Africa, the Eurasian Collared-Dove (*Streptopelia decaocto*) has established a widespread presence across North America due to human-assisted introductions.
Native to Asia, Europe, and North Africa, the Eurasian Collared-Dove now thrives across North America.
You’ll identify this medium-sized dove by its grey-buff to pinkish-grey plumage, distinctive black half-collar edged in white on the nape, and long, broad tail with prominent white outer feathers.
Measuring about 32–33 cm in length with a wingspan of 48–56 cm, it exhibits a plump body, small head, and pinkish legs. The bird typically weighs between 4.5 to 8.4 ounces, reflecting its moderately light build and agile flight capabilities weight range.
This species thrives in suburban and agricultural landscapes, often perching on telephone poles or visiting bird feeders.
Significantly, it drinks water by suctioning “head down,” a rare adaptation. Its rhythmic three-part coo and ground displays like head-bobbing help you recognize its presence in loose flocks.
Dark-eyed Junco
You’ll recognize the Dark-eyed Junco by its medium size, gray hood, white belly, and those distinctive white outer tail feathers.
It’s pretty easy to spot once you know what to look for.
These birds breed across boreal and montane forests, stretching all the way from Alaska down to the Rockies. Subspecies interbreed extensively in areas where their ranges overlap.
When winter rolls around, they migrate southward, often heading to open woodlands and even urban areas.
When it comes to food, the Dark-eyed Junco mostly forages on seeds right on the ground.
But during the breeding season, they mix things up a bit by adding insects to their diet.
Pretty smart, right?
Appearance and Size
The Dark-eyed Junco exhibits a compact, slender body measuring between 5 and 6.5 inches in length. It has a rounded head and a relatively long tail that stands out during flight.
You’ll notice its dark gray head, neck, and breast, contrasting sharply with a striking white belly. Males appear darker and more conspicuous, while females and juveniles show muted brownish-gray tones and streaked breasts.
Key measurements include wingspan of 7.1 to 9.8 inches, tail length of 6.1 to 7.3 centimeters with distinctive white outer feathers, bill length of 0.9 to 1.3 centimeters that’s pale pinkish in color, and body mass ranging from 18 to 30 grams. Males are typically about 5% larger.
These traits make the Dark-eyed Junco easily identifiable among medium-sized sparrows. The average weight is 0.67 oz (19 g) with an average wingspan of 9.25 inches (23.5 cm), reflecting its small and slender body.
Habitat and Range
Understanding where the Dark-eyed Junco lives complements what you know about its physical traits. During breeding, this species occupies coniferous or mixed forests spanning from Alaska and central Yukon east to Newfoundland, with southern limits in California, Arizona, Texas, Minnesota, Michigan, and New England. It favors open forest edges, clearings, and brushy ground cover, nesting near the ground in banks or fallen logs. Elevation-wise, it ranges from sea level to timberline, including alpine zones. The species is mostly migratory, although some southwestern mountain populations are permanent residents.
In winter, its habitat broadens to include weedy fields, open woodlands, and urban areas across southern Canada, the U.S., and into Mexico. Migration varies: some populations remain permanent residents, while others shift southward or downslope by up to 2,100 meters, seeking shrub or tree cover alongside open foraging grounds.
Behavior and Diet
Although the Dark-eyed Junco displays varied foraging behaviors, it primarily feeds by hopping on the ground and pecking through leaf litter or snow to locate seeds and insects.
You’ll observe it using four main methods:
- Hopping with frequent pecking and scratching to uncover seeds and insects.
- Flitting through low underbrush to glean food from twigs and grass stems.
- “Riding” grass seed heads down to feed on fallen seeds.
- Occasional aerial sallies to capture insects mid-air or from tree trunks.
Its diet is omnivorous, dominated by seeds outside breeding season but shifting to a protein-rich insect diet during breeding. At bird feeders, providing shell-free seed blends can help reduce mess and waste while appealing to the junco’s natural feeding habits. It prefers millet over sunflower seeds at feeders, reflecting its natural seed preferences.
Nestlings rely heavily on insects, while adults prefer seeds and plant material overall.
This behavioral flexibility enables survival across seasons and habitats.
Tufted Titmouse

Native to eastern North America, they’ve expanded northward into southern Canada. Usually non-migratory, they inhabit deciduous and mixed woodlands, parks, and suburban areas.
You’ll often see them forage acrobatically for seeds, insects, and caterpillars, frequently visiting feeders. They nest in tree cavities or nest boxes, lining nests with soft materials.
Pairs typically stay together year-round, and juveniles may assist in raising subsequent broods. Their distinctive calls are often described as “peter-peter-peter”.
Gray Catbird

While the Tufted Titmouse thrives in woodlands and suburban areas, the Gray Catbird occupies a different ecological niche characterized by dense thickets and shrublands across much of temperate North America.
You’ll recognize this medium-sized songbird by its uniform slate-gray plumage, black cap, and distinctive chestnut undertail coverts. Eastern populations are generally darker than western populations, adding some regional variation to their appearance.
Here are key points about the Gray Catbird:
- It forages near ground level, favoring leaf litter and dense shrubs, feeding primarily on insects in warm months and berries in colder seasons.
- The species exhibits strong territoriality, with breeding pairs defending nesting sites in thick vegetation.
- Its vocalizations include varied mimicry and catlike mewing calls, used for communication and territory defense.
- Nesting involves low, bulky cup nests with 3–5 pale blue eggs, typically producing two broods annually.
This bird’s adaptation to dense cover contrasts with other grey species you might know.
Northern Mockingbird
You’ll recognize the Northern Mockingbird by its distinctive gray to brown upperparts and paler whitish underparts.
Plus, it has two white wingbars that you can see when it’s flying. Interestingly, some owl species such as the Barred Owl use mottled brown and white coloration for camouflage, which helps them blend into their forest habitats.
One of the coolest things about this bird is its amazing vocal mimicry. It can reproduce dozens of different song types and often sings all day and night during the breeding season. The Northern Mockingbird is also known for its light green-yellow iris, which adds to its distinctive appearance.
On top of that, you might notice some pretty aggressive territorial behavior. They actively defend against predators and will even harass human intruders who keep coming near their nests.
