Ducking and Diving?

The Duck-billed platypus is one of the three existing Monotreme species in Australia. Monotremes are primitive egg-laying Mammals. Although the females produce milk, they do not have a defined breast. Zoos Victoria are reportedly training sniffer dogs to find occupied Duck-billed platypus burrows in river banks (https://www.theguardian.com/australia-news/2022/feb/04/weve-never-seen-a-platypus-lay-an-egg-sniffer-dogs-to-aid-researchers-by-detecting-occupied-burrows). The researchers training the sniffer dogs want to study how the platypus raises its young. For example, nobody has actually seen a platypus lay an egg. Any gleaned information could be very useful, especially if these endangered animals have to be raised in captivity. The sniffer dog handlers will, however, have to be very careful that their animals to not cause too much disturbance. The rearing of young can be a very sensitive process. Animals will abandon their offspring, if they feel threatened.
