Shake, Rattlers and Roll?

The historic drought, in the South-West of the US, has been good news for the Ramirez Rattlesnake Removal company. Rattlesnakes are now becoming common, in and around homes in Northern California (https://www.theguardian.com/us-news/2021/jun/26/california-drought-rattlesnakes-bears). The rattlesnakes are collected and 're-homed' in remote locations (let's hope they are not homing rattlesnakes!). The lack of water is predictably influencing the behaviours of many other wild animals. Bears can now be seen, in locations where they generally absent. The drought is also influencing the distributions of insects (such as mosquitoes in stagnant water remnants), fish and birds. Several animal-transmitted viral diseases of humans (such as West Nile) are also on the increase in the area. None of this should really be a surprise. The rattlers don't cause climate change.
