Field observations from 9th April 2022 to 13th April 2022

Spring is a major season in corvids’ life. They can be seen more frequently in places they quit during winter, such as the Botanical garden or other city’s parks, as they are looking for a good nesting place.

As zoosemioticians are mainly studying the interactions between species, and not only the behaviour of one precise species, it is interesting to observe how the changes in corvids also change the behaviour of species living with them. Ducks, especially, seem more cautious and more prompt to chase them away.

Corvus frugilegus are preparing in group for nesting seasons, and the nests are becoming bigger and bigger.

Corvus cornix seem more willing to stay isolate by pair. They are seen in parks, especially next to the river, gathering material to build their nest.

With the warmer climate, the complete melt of the snow and the young plants growing up, they can also be seen foraging for food on the edges of the river, dismissing trash cans for a moment.
