Observation details
Gathering mud to build up last years nests. Two active nests with white forehead spot seen on birds in nest openings. There was some uncertainty in my mind, whether these two nests from 2024, reported as used nests in April 2025, would be rebuilt and reused in 2025. The activity of these four Cliff Swallows confirms re-occupation of old nest in this case.
