2:40 PM | The owl who liked sitting on Caesar by Martin Windrow | Book Review | @GrrlScientist
A gentle and moving memoir by a man who shared his seventh-floor London flat with an unlikely companion; a tawny owl Unless you are Harry Potter, you probably don't live with an owl in your house. But historian and writer Martin Windrow lived with his "one true owl" long before Harry met Hedwig, as we discover in the charming book, The Owl Who Liked Sitting on Caesar [Bantam Press, 2014; Guardian Bookshop; Amazon UK; Amazon US/kindle US]. Written by a British historian and military expert […]

Scientifically described as Deuteragenia ossarium and dubbed as the Bone-house wasp, the species uses the chemical cues from ant corpses to ward off predators, by stuffing them into the crevices of its home. The species was discovered in Jiangxi Province in south east China.Wasps use a wide range of […]
