It is a long time since I last had a Wings on Wednesday entry. Amazingly, for the time of year, there has been a dearth of birds visiting the garden this month. Every now and then there is a rush of House Sparrows or Starlings and the Great Tits and Coal Tits are pretty regular but the numbers are well down so far this Winter.
One fleeting visitor was a Stock Dove. I haven't seen one of those for months so this was a welcome sighting.
Not quite so welcome was an early morning visit from a Sparrowhawk. This one was sat on the back of an old wooden chair right next to the Birdy Bistro. What I particularly noticed was the way it had its darker back facing outwards which made it blend in better with the fence in the background.
As soon as it spotted me it flew away to hunt for breakfast elsewhere.

Rain Gauge:
Only a little further with the rain gauge project. Added the ability to switch off the lCD readout in software. The collector is now outside and the electronics in the conservatory while I see how well it works. 3 mm rain recorded yesterday, 4 mm so far this morning.
The unit uses a 9V wall wart power supply but also automatically changes over to a battery during any power interruption - a far from unknown event in this area.
I have decided to change the Arduino Nano for a Mega as the Mega has internal memory I can use to store the results which looks easier to program than the SD card.
