Already starting from a monthly rate of 10.00 € you can take over a sponsorship. The amount for the respective sponsorship is calculated from the average costs incurred per bird species. It is used for a specific purpose and is therefore tax-deductible. You will receive a donation receipt and, much nicer, a sponsorship certificate as well as an annual admission ticket for the duration of the sponsorship. This allows you to visit your protégé regularly during regular opening hours.
