First seen at Battery Point on 3rd January so now in its' third week of residence. A female or immature I believe.
No interactions present.
Have a look at this website about black redstarts and green roofs in London. www.blackredstarts.org.uk/index.html
It shows how to create good green roof habitat that black redstarts can benefit from.
