"He got a surprise when he reached under the super mum and felt fur!" Fauna Rescue of South Australia (FRSA) wrote on Facebook. The duck seemed quite protective of the little squatter: a tiny brushtail possum who lost her mom. "Little Daisy had been kept warm all night by the duck who had the orphan tucked under her wing."
Maybe the duck could sense that the little possum, who only weighed 12 ounces, needed help. "All by herself in a big scary world, little Daisy the possum sought a warm, safe place to hide," FRSA wrote. "She clearly found the right place when she stumbled across a nesting box and crawled in with the duck. Rather than chasing the orphan away, the duck decided to not only accept her, but made every effort to keep the orphan warm and comfortable."
