One swallow does not a summer make

One swallow does not a summer make - Aristotle. 
But many swallows surely must! A couple of weeks ago we were extremely lucky to see swallows hunting insects over the river two days on the trot. At least, they had potential to be swallows..... or swifts...,. or some kind of martin. But swallow-like nevertheless! On both occasions the swarms of birds must have been at least 50 strong, although impossible to make much more of  judgement than that. They were such agile fliers; zooming like a bullet, then chopping and changing route in a fraction of a second. They were amazing to watch. Some flew so close, we could feel the whooosh on our faces.

Alas, with my 50mm prime lens they were nigh-on impossible to capture at all. This is perhaps the best illustration I can offer. Specks above a tree!  

Above: I love the little flowers atop these long stems.
Below: Catkins and feetkins

 New growth in the river and leafy reflections

The fluffy seeds from the tree above had all got caught up amongst the tiny flowers growing below it. So pretty.

  I love the light shining through the fresh new leaves

Once again, I'm seeing these tiny delicate purple flowers cropping up but have no idea what they are. Any suggestions?

There's beauty to be found everywhere!
