This gorgeous songbird is half male, half female

https://www.nationalgeographic.com/animals/2020/10/rose-breasted-grosbeak-half-male-half-female/?cmpid=org=ngp::mc=crm-email::src=ngp::cmp=editorial::add=Animals_20201015&rid=5DFCB8A357462614CEB0AA39E8AF8E74


Researchers trapped this rose-breasted grosbeak at Powdermill Nature Reserve in September. Its yellow side is female, and its red side is male--a conditional called bilateral gynandromorphy.

Exploring Eagle Hearing & Vision Capabilities To Reduce Risk At Wind Farms (great article! results haven't been published yet)

https://cleantechnica.com/2020/10/13/exploring-eagle-hearing-vision-capabilities-to-reduce-risk-at-wind-farms/

Quotes: "A Blind Spot Near the Top of Eagles? Heads" and "Eagles Can Hear Frequencies Ranging Across Four Octaves" and "Red-Tailed Hawks May Be Auditory Surrogates" (uh-oh! That means an eagle will always sound like an RTH in movies! ;D)


Figure 1. Visual field configurations of the golden eagle (left) and bald eagle (right). The Purdue University team found both species of eagles have a blind spot near the tops of their heads (bottom row). Illustration courtesy of Purdue University
