Despite all that is going on in our world, the seasons are moving on, and today this was very noticeable with the first sand martin of the spring being seen on the reserve. There are also several chiffchaff singing and at least 2 blackcap. Long-tailed tit are building in lots of places, I don’t think I have ever known so many pairs, probably a result of a very mild winter.
I saw my first grey-backed mining bee a few days ago, as is typical they were all males, who emerge earlier than the females. Today I saw the first female, she had not long emerged but was already attracting the attention of several males.
This bee has only recently recolonised the UK and so far has only a few sites, Blashford having one of the larger known colonies. It is one of the earliest solitary bee species to emerge and specialises in feeding on willow flowers, which are one of the very earliest sources of pollen and nectar.
The males wait around the nesting banks for the first females to emerge and try to mate as soon as they come to the surface. Mating itself seems to be a swift affair from what I saw today.
Over the next few weeks I will try to blog as regularly as I can, I am conscious that many people will not be able to get out and about, indeed it is quite possible these blogs may become about my garden or even just what I can see from the window before things are resolved. I will also be putting posts on Twitter, Bob Chapman @bobservablelife
Our human centred world may be tumbling about us as things we rely upon turn out to be nothing like as robust as we might have hoped. At the same time nature, much of which we have sacrificed in pursuit of growing what is now falling about us, will be carrying on, I will try to record some of that continuity as I come across it for as long as I can.
