Well, to be accurate, not really eating upside down but collecting food to take to a nearby branch to eat. This youngster seems to prefer this method for pecking off bits from the peanuts in the all mesh feeder. I'm pleased I bought this particular feeder as it gives a good opportunity to watch the acrobatic skills of Blue Tits, even from an early age.
Sorry I'm getting more than a bit behind answering comments and visiting blogs. A lot of my internet time has been taken up with finding the information and programs I need to get on with programming the Raspberry Pi. At last I have found a version of BASIC called FUZE which is more to my taste as most of my computer programming has been with various forms of that language. Sinclair BASIC on the ZX81 and ZX Spectrum, BBC BASIC on the BBC model B and GFA BASIC on the Atari ST so at least many of the structures are familiar though the remaining grey cell needs a good prodding to remember how to use them. I have reached the age where learning a new type of programming language is well and truly a very slow climb along a steep learning curve.

Have a great weekend observing the wildlife around you.
