About the Spot-crowned Antvireo
This bird is unique because it's the only one of its kind in its group, meaning it doesn't have any subspecies. It's very closely related to the streak-crowned antvireo. Some scientists even think they might be part of a "superspecies," which means they are very similar and share a common ancestor.
What Does It Look Like?
The spot-crowned antvireo is a small bird, about 10 to 12 cm (3.9 to 4.7 in) long. That's about the size of a sparrow! It weighs around 15 to 17 g (0.53 to 0.60 oz), which is very light.
Male Birds
Adult males have a dark gray head with many white spots on top. Their cheeks are grayish. Their back is grayish-olive, and they have a hidden white patch between their shoulders. Their wing feathers are dark grayish-olive with buffy-gray edges, and their wing coverts (the smaller feathers covering the main wing feathers) are blackish with white tips. Their tail is dark grayish-olive with white tips on each feather. Their throat, chest, and upper belly are white with dark streaks. Their sides are olive-gray, and their lower belly is whitish with a hint of orange-brown.
Female Birds
Adult females look a bit different. They have a reddish-brown head with dark spots. Their wing coverts are not as black as the males'. Their throat, chest, and the middle of their belly are pale buff (a light yellowish-brown). Their sides, lower belly, and the feathers under their tail are more orange-brown.
Where Do They Live?
The spot-crowned antvireo lives in specific areas. In Costa Rica, you can find it in the Caribbean lowlands. In Panama, it lives on both the Caribbean and Pacific sides. Its home continues into Colombia, especially near the Cauca River and along the Pacific coast. It also lives in northwestern Ecuador.
This bird prefers to live in the lower and middle parts of evergreen forests. It likes areas from sea level up to about 800 m (2,600 ft) in Costa Rica and Ecuador, up to 500 m (1,600 ft) in Panama, and up to 1,000 m (3,300 ft) in Colombia.
Behavior and Habits
Movement
Scientists believe that the spot-crowned antvireo stays in the same area all year round. It doesn't migrate to different places.
Feeding Habits
This bird mainly eats insects. It also enjoys other small creatures like spiders. Spot-crowned antvireos usually hunt for food in pairs or small family groups. They often join "mixed-species feeding flocks," which are groups of different bird species that forage together. They typically look for food about 3 and 8 m (10 and 25 ft) above the ground. They carefully pick insects off leaves while perched. Sometimes, they quickly fly out to grab prey from hanging leaves. They have even been seen following army ants for a short time to catch insects disturbed by the ants.
Life Cycle and Reproduction
The spot-crowned antvireo breeds between April and July in Panama. In Colombia, people have seen them building nests in late August. We don't know much about their breeding season in other areas. One nest found was shaped like a cup and hung from a tree branch about 2 m (7 ft) off the ground. This nest had two eggs, and both parents helped to keep them warm. We still don't know how long the eggs take to hatch or when the young birds leave the nest.
Vocalization
The spot-crowned antvireo's song is a fast, trilling sound. It starts with a slightly rising pitch, then falls a little at the end. The speed stays the same at first, then gets a bit faster towards the end. Its calls include a short, descending "chirr" sound.
Conservation Status
The IUCN (International Union for Conservation of Nature) has listed the spot-crowned antvireo as a species of "Least Concern." This means it's not currently in danger of disappearing. It lives across a large area, but its exact population size isn't known. However, experts believe the number of these birds might be slowly decreasing. No major threats to the species have been found. It's considered fairly common to uncommon in the places where it lives. Its habitat includes several large protected areas in each country where it is found, which helps protect them.
