Behavior
The Blue-and-black Tanager is a restless and energetic bird, known for its constant movement as it forages through the canopy. Unlike some of its more solitary relatives, this species is highly social and is frequently the 'core' member of mixed-species foraging flocks in the high Andes. They move with a sense of urgency, hopping quickly from branch to branch and occasionally performing acrobatic maneuvers, such as hanging upside down to reach a dangling berry.
While they primarily stay in the upper layers of the forest, they are surprisingly bold and will venture into garden edges or secondary growth if there is a reliable food source. They aren't particularly vocal, usually communicating with thin, high-pitched 'tsit' calls that can be hard to hear over the mountain wind, but their striking color makes them easy to spot once they break cover.

Camera Tips
To capture the Blue-and-black Tanager, height is your best friend. Because these birds prefer the mid-to-upper canopy and high-altitude scrub, placing your AI-powered camera on a ground stake won't yield results. Instead, mount your camera 5 to 10 feet up a tree or on a balcony overlooking a wooded slope. If you are in their Andean range, aim the camera at a flat, moss-covered branch which they often use as a 'runway' before hopping to fruit.
Food is the most effective lure for this species. They are highly attracted to platforms featuring halved bananas or plantains. To get the best AI recognition and clearest photos, position the fruit so the bird is forced to land in a well-lit area. Avoid placing the feeder in deep shadow, as the camera might struggle to distinguish the bird's black mask from its dark blue feathers without adequate light.
Lighting is critical for capturing the true brilliance of their plumage. Try to orient the camera facing North or South to avoid the harsh backlighting of the rising or setting sun. Dappled sunlight through a canopy can create a beautiful shimmering effect on their cobalt feathers, but ensure your camera's exposure settings are balanced so the black mask doesn't disappear into a dark blob.
Since these birds travel in fast-moving flocks, your camera's trigger speed is paramount. Set your device to a high-sensitivity mode with a short 'cool-down' period. Often, a 'scout' bird will arrive first, followed seconds later by three or four others. A fast recovery time ensures you capture the social dynamics of the entire flock rather than just a single, blurry departure shot.
