Usually they are. Haldane’s Rule notes that in hybrids the sex with two different sex chromosomes (XY) is highly likely to be sterile (there’s been a couple of male mules , but on rare occasions females (XX) can have viable offspring if the male they mate with is not a hybrid. Coywolves are generally fertile, tigon/liger females occasionally, female mules have reproduced the least and it’s only been documented a handful of times.

Mules have been documented to very rarely reproduce, and female ligers have been bred with both tigers and lions (making ti-ligers and li-ligers, respectively). In any case the math works at least as well as an elephant + duck mating.
