Field Notes: Amped Amphibians
Growing up, I had a friend who was extremely outgoing, had boundless energy, and liked to take more risks than most other people I knew. I remember asking myself, “Where does all that energy come from? What gives this person such a confident personality?” Bold, confident personalities in people can make them seem like ‘go-getters,’…
Field Frame Friday: Spotty Dads are not Shoddy Dads
A Spotted Sandpiper (Actitis macularius) father keeps a vigilant eye on his nearby nest from a creek-side perch. In Spotted Sandpipers, males take on most of the parenting duties, including incubating the eggs and protecting the newly hatched chicks, while females provide less parental care. One goal of my research is to determine how parental…
Field Frame Friday: Gobble Grabbin’
Wild Turkeys (Meleagris gallopavo) can be common backyard birds in some cities—like here in Davis, CA! Texas A&M PhD Student Amanda Beckman visited Davis as part of a study spanning the country to learn more about the genetic and behavioral impacts that urban living might have on Wild Turkeys, receiving some help in the field…
Field Frame Friday: Simply Ravenous
Common Ravens (Corvus corax) are famously smart, adaptable and opportunistic, and while these traits serve them well, they can often get them into trouble, too. What kind of trouble do you think the raven on the left got itself into to earn a bright blue tag and the attention of scientists? The tagged raven and…
Field Frame Friday: Who’s this chick??
A Spotted Sandpiper (Actitis macularius) chick shows off its shiny new leg band, which contains a unique ID number used by researchers to identify this individual. This chick will continue growing throughout the summer, migrate south for the winter, and perhaps return to its birthplace in the Mono Basin to breed next summer. [Photo and…
Field Notes: The First of Many Lasts
As I pack up my car on a breezy August day, I take one last breath of the cool, ocean air filled with scents of sagebrush and eucalyptus, realizing that while this wouldn’t be my last trip to the Marin Headlands, this is the last time I will be collecting data for graduate school. —…
Field Frame Friday: This is how I show my love – QUAIL
A California Quail (Callipepla californica) poses majestically on a shrub. California Quail participate in brood-mixing, where multiple female quail will raise multiple offspring (related and not-related) in communal family groups. It is suggested that females involved in communal family groups also live longer than those in single family groups. There are benefits of being a…
Creature Feature: American black bear
We’re about to finish checking our bird traps at Tioga Pass when I spot it– a moving black lump in the upper right hand corner of my eye. We freeze. “Holy–” I say. “Is that…?” I slowly raise my binoculars. It is. Standing on a boulder, huffing its huge steaming snout in the morning air,…
Field Notes: Four Field Perspectives
Field biology is almost always a team endeavor. Field crews often include people with different levels of experience and biological backgrounds—and each member brings something valuable to the team, from budding young scientists to experienced researchers. Going into the Summer of 2022, my second field season researching Spotted Sandpipers (Actitis macularius), I was nervous ….
