Sound h2485. Song of Mouse-colored Tyrannulet.
The habitats was secondary arboreal Caatinga, 10-20 years old.
Vocalizations from at least two birds, that chased each other around in the small Caatinga trees,
a few meters above the ground. I saw one bird performing a wing display. This was possibly courtship behaviour.
The spectrogram show a 3-sec extract of the recording.
