At nightfall, a bird looks like an insect

The noitibo-European feeds on insects and goes into activity at dusk and at night. Its continuous singing can remember the sound of a cicada. In Portugal it is a summer bird, mainly associated to the north and the transition between forest and open spaces. The Cavez record shows a sentence attributed to this species by the iNaturalist community. It is a trace: it is not a photograph of the entire bird, nor does it prove the existence of a nest at that point. Curiosity begins in a feather and continues in the sound landscape.

The long wings and tail can be perceived in silhouette, but the little light hides details. Aves de Portugal’s record explains that females do not show white spots on the wings of males; juveniles do not have them either. The absence of a brand alone does not solve age and sex.

The source describes a late arrival and the easiest corner to detect in May and June. It is a Portuguese standard, not an agenda of sightings in Cavez. The recorded penalty does not allow to know when the bird sang, where it nested or how long it remained in the zone.

In order to know travel, investigators need another type of registration. The BTO presents follow-up studies that have located an important winter area in grass and shrub landscapes south of the equatorial forest, especially in the Democratic Republic of Congo. It is information on birds accompanied by those studies, not the proven destination of the specimen associated with the sentence of Cavez. A penalty documents a trace in one place; the follow-up allows you to connect positions over time and study movements.
