The Common Redstart is a hole-nester but less fussy than the flycatchers — it readily takes both round-hole and half-open boxes, as long as there is a clear approach and a suitable position near open ground.
| Measurement | Value | |---|---| | Entrance hole | 32–34 mm (or half-open/oval front) | | Internal floor | approx. 12 × 12 cm | | Box depth/height | 20–25 cm | | Mounting height | 2–4 m |
Placement: hang the box on a trunk in half-open terrain — edge zones, old gardens, avenues and sparse pine woods suit it well. The Common Redstart hunts a great many insects on the ground and therefore needs open grassland or sparse vegetation within reach of the box.
Light aspect: the species tolerates a sunnier and more open position than flycatchers and tits, since its natural breeding habitats — woodland edges
