Female Blackbirds are busy eating our ‘Joseph Rock’ Rowan berries. Female Blackbirds are quite aggressive in the breeding season, when competing for good nesting sites, and they do most of the nest building and all the incubation. Breeding is from early March till July. Only 30-40% of broods successfully raise young, though the percentage is higher in town nests than in rural areas, despite clutches being smaller. Pairs stay together for life. Conditions: Sun with increasing cloud. Temperature: Max 6- Min 2C.
