AWWI Technical Report: A Summary of Bird Fatality Data in a Nationwide Database

https://awwi.org/wp-content/uploads/2019/02/AWWI-Bird-Technical-Report-02_25_19.pdf


Some Takeaways

The 15 most reported of the 281 species constituted 48.8% of all fatality incidents. American kestrel and red-tailed hawk were in the top ten species with the most reported fatality incidents and were the most frequently reported raptor fatalities across almost all avifaunal biomes.

Seventeen golden eagles were reported in 11 scheduled searches.  Twenty additional golden eagles were reported as incidental finds.  No bald eagles were contained in the AWWIC database. Fatalities of the bald eagles at wind facilities have been reported in the literature and more are known to have occurred since this publication.

Conclusion

"Because of their life history attributes, diurnal raptors are a group of concern. Collision risk appears to vary considerably within this group, and this variation will be evaluated with additional data and further analysis."

Abstract: Modelling the risk of collision with power lines in Bonelli's Eagle Hieraaetus fasciatus and its conservation implications

https://www.cambridge.org/core/journals/bird-conservation-international/article/modelling-the-risk-of-collision-with-power-lines-in-bonellis-eagle-hieraaetus-fasciatus-and-its-conservation-implications/DE36CF8D56F0A3829B2017262C627D60

Takeaways:

"...the risk of collision was mainly determined by eagles' home range use..."

"...the risk of collision increased in open habitats, far from urban areas that were good for hunting, and in cliff areas used for breeding and roosting, where eagles fly at a lower height..."

"These results suggested that power line collisions might be more important than previously reported as a cause of mortality for the species..."

The changes in color are as light as the lightest species and as dark as the darkest species in the entire genus -- and this genus has been evolving for millions of years.
