Early Summer was great for welcoming back our migrant birds. Areas of the Peak District in particular for me are a great place to go and find them. On a warm June morning you should be able to pick out the calls of Common Redstart, Tree Pipit, Common Sandpiper and Pied Flycatcher. Of course, that does require you to be in the right area, and it's not always guaranteed. They can be there, and just not singing or calling. Or more commonly they're spending their time at the top of the canopy looking for insects. Add in the fact that the leaves are now out to make it even more difficult to spot. It does mean that I spend more time out looking than I would normally, especially if I've not been successful. Not that I'm complaining. Outdoors is when I like to be most.
