Let there be lights, to help migratory cranes avoid power lines (great idea!)

https://news.mongabay.com/2019/07/let-there-be-lights-to-help-migratory-cranes-avoid-power-lines/


Hundreds of thousands of sandhill cranes stop along the Platte River in the midwestern U.S. to rest and refuel on their annual migrations. They often travel at night, so the ACAS system's aim is to help cranes and other birds see power lines and other human structures in the dark, enabling them to safely reach their destinations.

New science confirms warming climate bad for forest birds

Native birds becoming confined to higher altitudes by climate and pests

Paper: Thermal squeeze will exacerbate declines in New Zealand's endemic forest birds

https://www.sciencedirect.com/science/article/pii/S0006320718315623?dgcid=author


Maps of New Zealand showing (a) land (grey) and present indigenous forest cover (black) on the three main islands; and, within each of the 2155 10 ? 10 km squares for which we have occupancy probability estimates for bird species, (b) percent indigenous forest cover and (c) median mean annual temperature.


Kiwi are among the native birds caught in a "thermal squeeze" (file photo).


In March 2015, 23 orange-fronted parakeets/kakariki were released inn the Hurunui River south branch. Kakariki are vulnerable to habitat change.

The paper below was cited in a recent article about whether to wear black or white clothing when it's hot. It's complicated but, so far, it seems it doesn't matter.
