1. Great-Tailed Grackle
The Great-tailed Grackle is a medium-sized bird native to North and South America. It belongs to the family Icteridae, making it closely related to two other species of grackles – the Boat-tailed and Slender-billed.
They are highly social birds which often appear in large flocks or colonies.
Their plumage ranges from glossy black with blue or purple iridescence, through brownish-grey shades depending on location.
In some areas, they have been known as “blackbirds” due to their predominately dark coloring.
This adaptable species is also renowned for its distinctive long tail feathers – hence its name.

2. Ringed Kingfisher
The Ringed Kingfisher is a large, vibrant bird that can be easily noticed by its loud call. It’s found in tropical regions from the lower Rio Grande Valley of southeastern Texas to Central America and even as far south as Tierra del Fuego.
This ground-dwelling species prefers to inhabit open areas near water bodies like streams, rivers, and lakes which provide them with plenty of food such as fish, amphibians, crustaceans, and insects.
In 1888 it was first identified by ornithologist Frank Chapman who noted its distinct ring pattern on the breast area.
The upperparts are dark blue while underneath they have white spots around their neck and belly region along with pale brown wings tipped in black stripes making this species unique among other kingfishers.
They may look intimidating but these birds play an important role for humans since they help control insect populations thus helping maintain a healthy balance within our ecosystems.

Its call is also distinctive as it makes high-pitched whistles to communicate with other members of its flock.
It prefers wetland habitats such as marshes, ponds, and lakes where they feed on seeds and aquatic plants like wild rice or pondweed.
During breeding season these birds form monogamous pairs nesting in trees near bodies of water.
They are migratory birds but some may remain year-round depending upon local climate conditions making them relatively common sights in certain areas during winter months when most other ducks have migrated further south for warmer weather.

8. Curve-Billed Thrasher
The Curve-billed Thrasher is a medium-sized bird native to Mexico and the southwestern United States. It lives mainly in desert areas, where it can be found foraging on the ground for its insect prey.
Its name comes from its curved bill, which aids in rooting out insects and other food sources.
The species has several subspecies that are geographically separated throughout much of their range; allopatric speciation likely played an important role here as well.
Despite being non-migratory, this thrasher will sometimes travel long distances when resources become scarce or during courtship displays with potential mates.
A successful predator of grasshoppers, beetles, and other arthropods, the Curve-billed Thrasher plays an essential role in maintaining healthy ecosystems by controlling pest populations.

The bronzed cowbird is a small icterid species that was formerly known as the red-eyed cowbird. They are found breeding in several states of the US and many Central American countries, including Panama.
You may often spot them in farmland, brush, and feedlots, where they tend to forage. These birds prefer open habitats when not breeding and roost in dense woods.
They exhibit brood parasitism, laying their eggs in other bird species’ nests, and leaving their young ones to be reared by the host birds.
The bronzed cowbird’s diet mainly comprises seeds, grains, and insects. These birds are known for their metallic green and bronze plumage and their characteristic high-pitched whistle, which they use for communication.
They make an interesting addition to the avian diversity of their range.
