Image of the day – 156
What’s in an image? Sometimes quite a lot, more than meets the eye. I’m posting an image every few days.
Here’s something you may never have seen, unless you’re a farmer or a vet – a calf suckling from its mother. When we lived in St Neots, there was a footpath running past our back gate in Eaton Ford and running very straight to the churchyard of St Mary’s in Eaton Socon. The path led past a large field, Bedfordia Meadows, and sometimes cows were kept in this field.
On one particular day in 2012 I was using the footpath and this cow and her calf were close up against the fence. I was able to take the photo without even stepping off the path. I’ve been working my way through my photos from July 2012 recently, looking for images for articles like this one. And it seemed to me that many of you might like to see this moment from a summer’s day 13 years ago.
For the cow and the calf this is a matter of life and death. Without the mother’s milk a new-born calf would not survive long. Milk contains the water and all the nutrients needed for the calf to grow and become capable of drinking water and eating grass for itself. In the wild, like all mammals, the cow would stop producing milk once the calf stopped needing it. But domesticated cattle have been bred to produce milk for much longer and a cow would quickly be in pain and in danger of serious infection if not regularly milked twice a day.
Mammals provide milk, birds lay eggs
Both dinosaurs and mammals developed from early reptiles. At the time of the Cretaceous extinctions caused by the impact of the famous asteroid, when all the large dinosaurs died out, there had long been early mammals and some of the smaller kinds survived. One branch of the dinosaurs survived as well and we are all familiar with them, they are called birds! A number of small reptiles and amphibia survived too so today we have toads and frogs as well as crocodiles, alligators, lizards and the snakes. But most air-breathing vertebrates in the world today are either mammals providing milk to their young, or the egg-laying birds.
That asteroid changed everything!
