What’s out of sight is out of mind. It’s perhaps not surprising that relatively rare predatory birds like owls are faithful to their sexual partners. After all, if they don’t come into contact with many other owls, any temptation to stray would be easier to resist.
For one species of owl, though, the lure of a different sexual partner can be just a few steps away. The burrowing owls of Argentina have embraced town life, nesting in large numbers in urban areas near cities including Bahía Blanca. While owl nests in rural areas can be separated by as much as 15 kilometres, urban nests may be little more than 10 metres apart. So do urban owls stay faithful, like their country cousins?
Burrowing owls get their name for their tendency to set up home in abandoned mammal burrows – the only owl known to do so. They stand a little over 20 centimetres tall, on a pair of strikingly long legs. Those come in handy during hunts, during which the owls often run down insects and small mammals on foot rather than swooping on them from above. read more
