A gloriously sunny day today. It felt uplifting to be out and about for a walk in this sunshine. On an early afternoon walk with the dogs, I noticed the Spring song of the robin. According to the RSPB :
Only for a short period in late summer while they are moulting and inconspicuous do robins stop singing. Both sexes sing.
As with the nightingale, the song is usually delivered from a concealed perch within a bush or a tree exposed perches are infrequent. Autumn and spring songs are distinctly different. The autumn song starts after the moult, from late summer onwards. It is more subdued and melancholy in its tone, while the spring song is powerful, confident and upbeat.
The spring song can start as early as mid-December, reaching full force in spring. Its purpose is two-fold: to defend a territory and to attract a mate. Therefore, spring song is far more powerful in males.
