These 'eggs' are spying on whooping cranes to boost survival

https://phys.org/news/2019-04-eggs-spying-whooping-cranes-boost.html


In this March 6, 2018 photo provided by the Louisiana Department of Wildlife and Fisheries, a data logger egg is seen at left and a real whooping crane egg at right, in Allen Parish, La. Spy eggs may help Louisiana biologists learn why some whooping crane chicks die in the egg, while others hatch. State biologists swap egg-shaped data loggers for one of the two eggs that many cranes lay. The real eggs are incubated at Audubon Nature Institute until they're nearly ready to hatch. Then biologists swap them back. The fakes give up their data through an infrared connection. (Eva Szyszkoski/Louisiana Department of Wildlife and Fisheries via AP)

Birds' surprising sound source

Paper: The evolution of the syrinx: An acoustic theory

https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.2006507


Fig 1. Schematic (not to scale) of the experimental setup testing a physical model (blue region) in a syrinx or larynx position.
The microphone was placed 10 cm downstream from the opening of the vocal tract. Pressure transducers (P1, P2) were placed below the respective sound sources. A 15l expansion chamber simulated acoustic properties of the lung. Flow rate was measured upstream from the expansion chamber. Trachea length was varied between 0 cm and 248 cm.

Fifty-year study shows climate change is pushing UK wildlife out of sync

Abstract: Spatial and habitat variation in aphid, butterfly, moth and bird phenologies over the last half century.

Pied Flycatcher is thought to be struggling due to increasingly early emergence of the prey it relies on to feed its young (Kev Joynes).
