With the eggs not having hatched yet, you would expect it to be Spring or very early summer. Their breeding habits do vary a little and these were already unusual in deciding to stay in British waters (however this is more likely to lead to them erring on the earlier side and being quite young birds). I'm not sure AR will have given it this much thought!! Generally they head off from UK waters around April (ish) and breed in May/June. First winter juvenile birds can be see around UK waters again in October.
