New paper alert! The AVONET database was just published in Ecology Letters (get access here). This gargantuan effort led by Joe Tobias and involving 115 authors from more than 100 institutions provides morphological, geographical, and ecological trait data for ALL of the world's >11,000 bird species! Super proud to have played a small part in it.

In May 2020, some friends and I stumbled upon a Tufted Titmouse (Baeolophus bicolor) plucking fur from a sleeping Raccoon (Procyon lotor) in Allerton State Park, IL. My curiosity was piqued, and I started digging around in the scientific literature to see if this behavior had been previously documented. I found that it had been reported only about a dozen times sporadically throughout the decades, giving it the appearance of an uncommon chance occurrence. However, a cursory search of YouTube yielded dozens of videos of titmice and other birds plucking hair from dogs, foxes, and even humans, demonstrating that this was a commonly known behavior in the birdwatching community. We just published a review paper on this behavior, which we termed "kleptotrichy", from the Greek roots klepto- ('to steal') and trich- ('hair'), in the journal Ecology. Check it out here, and also check out some of the awesome media coverage we have received!!! |

Big news!!! My collaborators at University of Wyoming (Corey Tarwater and Patrick Kelley) and Universidade Federal de Pelotas (Jeferson Vizentin-Bugoni) and I just got awarded an NSF grant! Over the next three years, we will be working to understand the evolution of behavior and species interactions in army ant-following birds across the isthmus of Panama. We will hire two PhD students to conduct cutting-edge experiments to explore the impacts of species loss on the structure and stability of ant-following bird flocks. Please contact me if you are interested! |

Second paper out this month! This was a super fun collaboration with co-authors, Mark Hauber (UIUC), Floria Mora-Kepfer Uy (University of Rochester), and Jeff Hoover (Illinois Natural History Survey) looking at brood parasites and where they fall out on the natural enemy continuum. We argued that they represent a functionally distinct class of natural enemies, merging traits of both predators and trophic parasites. My first foray into the realm of parasitology - check it out here!!! |

New paper alert!!! We just published a comprehensive update of the distribution and abundance of the locally endangered Micronesian Starling on Guam. We found that the population has increased ~15-fold (i.e. from ~100 to ~1500 individuals) since the last survey in the mid-1990s, and starlings appear to be expanding into urban areas throughout northern and central Guam. Overall, it is a conservation success story, with the population recovery likely due to the starlings' tolerance of human disturbance coupled with snake control measures at our study site on Andersen Air Force Base. This paper was a collaborative effort between Colorado State University, Iowa State University, U.S. Geological Survey, and Guam Division of Aquatic and Wildlife Resources. You can find it here! |

When I first arrived to the island of Guam in 2017, I met Martin Kastner. Martin had been working as field manager for the Micronesian Starling nest box project for the past year and a half, and I quickly realized that he had a keen eye for animal behavior and natural history. One day, while out in the field radio-tracking starlings on Andersen Air Force Base, Martin drew my attention to what he termed 'fruit islands' - small seedlings or saplings growing out of the bases of larger overstory trees scattered around the housing area. He speculated that these propagules were likely being deposited by the starlings - Guam's only remaining native frugivore - and we devised a simple way to test this. We compared seedling communities under overstory trees between Andersen (starlings present) and a nearby control site (starlings absent), and found essentially no dispersal or regeneration occurring at the control site. These findings confirmed our supposition that starlings were likely dispersing the seeds, providing concrete evidence that even a very small, remnant population can still provide substantial ecosystem services. We just recently published this short and sweet paper in Biotropica - check it out here. Just goes to show you that careful natural history observations can go a long way towards understanding ecology. Congrats to Martin and all!! |

In 2015, we were invited to do a review paper on birds that follow army ants. Six years later, it is finally published in Ornithology's Special Feature issue "Advances in Neotropical Ornithology"!!! It has been a long and winding road, but a special thanks goes out to my co-authors - Janeene Touchton, Ari Martinez and Patty Rodrigues - for having the perseverance to bring this one over the finish line. Super proud of this review - you can find it here.

I was recently featured in a Q & A called 'Meet the Scientist', published in the August 2020 issue of BBC Wildlife Magazine! The interview focused on our article "Rapid colonization and turnover of birds in a tropical forest treefall gap", which was recently published in the Journal of Field Ornithology.

I presented collaborative work at the virtual North American Ornithological Conference on long-term declines of tropical birds in intact forest of central Panama. The bottom line - 70% of the 57 bird species we modeled declined in abundance over the 43-year sampling period. These trends are very concerning given they occurred in a large, forested preserve (the 20,000 hectare Soberanía National Park).

We just published a paper on the responses of Neotropical birds to a large treefall gap in Panama!
Following gap formation, hummingbirds and understory frugivores increased in abundance and species richness very rapidly (within five months) but only persisted in the gap for 1.5-4 years before returning to pre-treefall levels.
