Paper: Peregrine Falcon Eggs : Egg Size, Hatchling Sex, and Clutch Sex Ratios

https://pdfs.semanticscholar.org/9e3e/57cbdc43a77d5d856209a9d3abb8e8fbc3e7.pdf?_ga=2.114036737.763357598.1543610396-1765627468.1542402478


Relationship between egg length and egg breadth for 366 Peregrine Falcon eggs collected from wild nests and incubated in captivity (1976-1990). These two variables were only weakly (although significantly) related, so both were used in subsequent multiple regression analyses as explanatory variables


Sex ratio (proportion of males) in first (n = 29) and second (n = 10) clutches of Peregrine Falcon eggs where sex was discernible for all eggs within a clutch. Proportion of males did not differ from 0.5 for either first or second clutches.

Paper: New Rodenticide on the Block: Diagnosing Bromethalin Intoxication in Wildlife

https://escholarship.org/uc/item/87p45686

Quote: "Bromethalin is a neurotoxicant which is not thought to cause secondary poisoning."

Quote: "Although there have been no confirmed
cases  of  secondary  poisoning  from  bromethalin,  there  is
very  little  data  to  exclude  this  possibility  (Jackson  et  al.
1982).  Continued monitoring of carnivores will be helpful
in  determining  the  occurrence  of  secondary  exposure."

Scientists discover how birds and dinosaurs evolved to dazzle with colourful displays

https://www.sciencedaily.com/releases/2018/12/181210101938.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


Two of the fossils sampled for the study with the fossil melanosomes found in each fossil (scanning electron microscope images). Scaniacypselus to the left and Primotrogon to the right. Melanosome shape varies in the different samples, and is indicative of color. The sample furthest to the left was predicted to be iridescent.

Bird ancestors first evolved shiny feathers around 150 million years ago when certain dinosaurs started going up into trees, according to new research. Pictured is a Masked Trogon in Ecuador
