Polar animals

These days, what with climate change, it’s worth noting that animals at the poles are at a special risk of extinction. Simply put, they have no where to go when their habitats warm beyond their ability to cope. Take for example, penguins.


Observation affects reality

A nighthawk female defends her nest from me.

That which we study is inevitably affected by our presence. This is something that I considered when setting my nest check protocol. The typical interval for checks is 3-5 days. However, nighthawk rooftop nests are visited frequently by maintenance workers, construction workers, window washers and helicopters. So, instead I opted for the 6-7 day interval and left nest cameras to monitor the time between my visits.

This concept, that observation affects reality, is nothing new. Physics has a long history of addressing this.
