Which species should you count?

The autumn is already in full swing. Whether you are going to your favourite excursion area or keeping a lookout at an observation post, don't forget to fill in a complete observation list! But for which species do you need to fill in the most accurate figures possible? You can count all species if you want, but if it is too tedious, please count at least the species in category A (those with a red dot in front of their name). For analyses such as the calculation of the presence index, numbers are essential. For such an analysis, 200 counted Honey Buzzards weigh 200 times more than a simple cross that confirms the presence of the species. If possible, always count species A, or give at least an estimate or a minimum number.

We wish you great migratory bird observations
