Girl power: Red-shouldered hawk parents invest more in female offspring‎

A new study published in the Journal of Raptor Research, titled "Factors Influencing Nestling Sex Ratios of Suburban and Rural Red-Shouldered Hawks, 2004–2016," finds that hawk parents prioritize producing female offspring when conditions are optimal. This means that higher quality territories could result in more females, offering biologists clues about habitat health, which is important intel as the species adapts to urban environments with increasing frequency.
