How intelligent are crows

Intelligent corvids

You are looking for something about the most intelligent corvids. Is it the magpie or the raven, the carrion crow or the jackdaw, the carrion crow or the rook or even the jay? I dont know. I've been watching corvids for years and everyone is intelligent in their own way. I have already reported on it several times, e.g. intelligent crow in nature or crow cracks nuts. During the white-tailed eagle protection in Hamburg, I saw carrion crows throwing small sticks on the eagle. I have also observed crows that mainly feed on mussels, fish and woolly crabs from the Elbe in Hamburg. And how they do it, you can find out here.

Here you can participate in my observation of how the crow opens the mussel (pond clam) without much effort in order to get to its contents. For a better understanding, I will show you many photos that I took during my observation. The crows on the Elbe have adapted their daily routine to the ebb and flow of the tides in Hamburg. At high tide, the crows sit on their hide, clean their plumage, drive intruders out of their territory or keep an eye on the surface of the water. It could be that a dead fish is swimming in the water or being propelled on the bank.

When the water runs off, the embankment between the stones is already searched for mussels, larvae, worms, snails, crabs and small eels. Not only do the crows look for eels, but also the seagulls and the white-tailed eagle. More about this on my page sea eagles fishing.

In the Elbe there are also some mussel beds that can be seen when the water is extremely low. And where the mussel beds are, the carrion crows know too.

Not far from the mussel banks, the carrion crows also find large pond clams in the harbor silt of the Elbe. To get to the contents, the carrion crows and carrion crows fly up and drop their prey so that it crashes on the ground. This method of accessing the content is often seen in corvids.
But now I come to an intelligent carrion crow who uses a new method that has that in itself. The crow looked around carefully to see if it was not being watched by other corvids as it was going on. When she was sure that she was not being watched, she took a pond clam out of the silt and put it back on the surface and walked on. I thought to myself "What is this about"?

A little further on, the crow fetched another pond clam from the harbor mud in Hamburg. This time she didn't put the clam down and walked on, but opened the clam without any problems and ate the clam meat. Why was the crow able to open the shell without any problems? I asked myself the same. And so I observed the carrion crows even more closely over the next few days. I wanted to know why the carrion crow can easily open the clam.

What's the secret? Before long the secret was out. If you are out and about every day and make observations in nature, the simplest things do not immediately come to your attention. As in this case. The secret is the water and the sun. The sun shines on the mussel for hours during the ebb (low water) and so it dries out (overheats) and dies. Now it is easy for the crow, because the mussel does not offer any resistance when it is opened. This also explains why the crow simply left the first shell lying there. The mussel had to die off first. The sun accelerates the drying out of the mussel on land.

During my observations, I often saw how the crows occasionally picked up clams and crabs and flew away with them. What were they going to do with it? Do they bring their prey to the nest? I looked for another location from which I could see where they were flying to with their prey. The crows did not bring the mussels and crabs to their nest, but hid them between stones in the bank. The carrion crows have created a store for themselves between the stones. Before placing the crabs in it, they removed their legs. So the crows were sure that the crabs could no longer run away.
Now someone should say "Carrion crows are not intelligent".

Not only the corvids, but the fox, the goosander, the gray heron, the gulls, the middle saws and even the sea eagle eat the woolly crabs. A couple of photos.

The carrion crow is a subspecies of the carrion crow. There you will also find a small profile about the carrion crow.

Also have fun on my pages, such as raising young sea eagles or young buzzards.

If you want to find out something about the knowledge of birds (intelligence), visit my pages: What do birds and intelligent crows know. My site is very useful for projects in kindergarten, district school, high school, university and school for lectures and essays in biology, in zoology, in specialist classes, for worksheets, for species profiles and for presentations or for an essay in biology lessons popular. Here you will find everything for your profile template (elementary school, secondary school, high school) about birds.
There are extra bird pages for the children in preschool and for the children in primary school, e.g. with pictures of chicks or bird portraits. At the bottom of the page you will always find a list of other bird watching.

We have had our most beautiful bird observations in Europe in Iceland, in Scandinavia (Norway, Sweden, Finland, Denmark), in Holland, in England, in Poland, in Austria, in Switzerland, in Belgium, in Ireland, in Italy, in France, in Portugal, in Spain, in Greece, in Germany in Berlin, in Hamburg on the Elbe, in Bremen, in North Rhine-Westphalia, in Baden-Württemberg, in Saarland, in Rhineland-Palatinate, in Bavaria, in Hesse, in Schleswig- Holstein, Mecklenburg-Western Pomerania (Lewitz), Thuringia, Brandenburg, Saxony-Anhalt and Lower Saxony.
