Just recently a dataset of 30.000+ bird records from Azerbaijan has been uploaded to eBird and is now ready for getting explored! This online database provides an easy opportunity to prepare birding trips and find out what to expect. Nevertheless, there are still ornithological gaps of knowledge, so if you intend to visit Azerbaijan it would be fantastic if you could make your observations available, too!
