MPs are finally heading off, a little belatedly, on their summer holidays. I imagine they will all take care to avoid being photographed in overly glamorous locations, lest they are accused of being frivolous in a time of national austerity.

As well as exercising caution over where they are seen, they will presumably also be careful about who they are seen with. I imagine that the soirees of the so-called Chipping Norton set will be rather low-key affairs this summer.....

They could do worse than heading up to Scotland - always glorious at this time of year. If you're planning to be there too, you could help us by looking out for some of our rarest birds.

For the past couple of months, surveyors have been  scaling some of Scotland's highest mountains in search of  two species: The dotterel and the snow bunting.

These species only breed in the UK on our highest ground - the Scottish mountain tops. Because of this, they are vulnerable to climate change and associated changes in habitat and prey abundance. Already restricted to the highest, coolest conditions, they may find it difficult to move elsewhere in the UK if temperatures climb.

The RSPB and Scottish Natural Heritage are encouraging walkers to keep their eyes peeled for these species. The dotterel is found most commonly in the Cairngorms. It's a fascinating little wader that reverses traditional gender roles. The females are brightly coloured and take the lead in courtship, before leaving the smaller, drabber males to incubate eggs and raise any young.

Snow buntings are very rare - and quite hard to spot. But if you are likely to be heading to the tops of Scotland's highest mountains, do keep a look out.

If you're lucky enough to catch a glimpse of either species, please make a note of how many birds you've seen, along with the date and location (including a grid reference, if possible) and email the details to dotterel@rspb.org.uk

Admittedly, if your idea of the perfect Scottish summer is a few good nights out in Edinburgh, you probably can't help too much. But if you're more interested in Munros and mountains than in Festivals and Fringes, then please help us to look out for these rare and elusive birds.
