|What creeps and signs? What a couple dances around a tree? Having a short walk to my favourite park and it takes only few minutes to look around to notice that singing creatures not only fly but creep on a tree cortex too. Especially around feeders area however when the snow melts - not only. So here we go: in the parks we can find a couple of treecreeper species, although very difficult to distinguish even for people interested in ornitology: treecreeper and short-toed treecreeper. They differ with subtle details which I am not going to dive into. During the last weekend park walk, although I do not know which of them I was observing, they must have felt the spring already - a couple was dancing around the tree, creeping higher and higher.It was hard to follow them even with a naked eye, let alone with a telezoom.|
|Not much experienced eye can mistake them with a nuthatch, which like treecreepers moves on the tree cortex, but this one can also go with his head downwards, like no other can do.|
|On the other hand the nuthatch ca be imitatted by a great tit, however those only sometimes just stick to the tree cortex while targeting pieces of food in the feeder. One will not see them creepeing though.|
