Sparrows for Linda

Mon Feb 8, 2016, 5:49 AM
My very good friend Linda, LindArtz :iconlindartz: while admiring some of my recent bird images from my Tanzanian Safari asked about sparrows, as these are one of her favourite birds. I didn't photograph any in Tanzania, but I promised to snap any that I came across. Here is a very short selection of house sparrow (Passer domesticus) images taken at my cottage in Scotland, during very wet and windy weather. Light conditions were poor, resulting in high ISO settings with the introduction of some noise. All the images are of male sparrows, the females being far to canny to come out in foul weather. We in the UK think of sparrows as those small brown noisy birds that flit about our gardens, and we barely pay attention. However, close up photographs show them to be colourful with a grey cap, brown or chestnut coloured mantle (back) and black bib and chest. The males have white spots or streaks above their eyes, and some have white or very light wing flashes. They flock with other birds, particularly tits and chaffinches, and are seed eaters.

The second bird in the lower two shots is a male chaffinch in the process of dropping the peanut that he had carefully extracted from the feeder. Note also that the sparrow has damaged tail feathers.

I hope you like these, Linda.

Thank you for the watch.

No probs. Have you ever exhibited at any of the galleries around Dumfries? I feel I've seen your work somewhere and I kno and buy from galleries in Castle Douglas and Kirkcudbright.

david-harris Featured By Owner 5 hours ago
Have not exhibited in the Dumfries area. Have mainly shown work in the north of Scotland. Went to the Dumfries and Galloway area for the first time last October to pick up three Brown-eared pheasants from a breeder in Stranraer.

My pleasure, Maresa. Did I say that we are visiting KZN in July? I guess you're the other side of the country or we could have had a meet.
