Birdwatching Tips
Best Locations for Spotting Collared Whitestart, Collared Redstart
In Costa Rica, head to highland areas like Monteverde Cloud Forest Reserve, Cerro de la Muerte, and the Talamanca Mountains. Poás Volcano National Park and Tapantí National Park are also excellent locations.
Best Time of the Year
Year-round in Costa Rica, though activity may increase during the breeding season (March to July).
Common Behavior
Look for its characteristic tail-fanning behavior while foraging. It tends to be active, often found flitting through the mid-level canopy or forest edge.

Binoculars with good close-focus capability are ideal for observing its rapid movements. A lightweight camera with fast autofocus can be useful for photographing its distinctive tail fanning.
Breeding and Nesting Behavior
Breeding Season
In Costa Rica, breeding typically occurs from March to July, during the rainy season when food is plentiful.
