Guest feature | How ringing data can help improve geolocator studies
Thanks to their light weight, multi-sensor geolocators are ideally suited to study the migration patterns of smaller birds. Indeed, while GPS trackers provide accurate data, their cost is prohibitive and their weight still restricts their use to larger birds (100grams and above). Read More
Guest feature | Post-fledging ecology of endangered Golden-cheeked Warblers
Ever since I was a child I’ve had a passion for wildlife conservation, especially endangered species. It was almost too good to be true, then, when I started my thesis work on an endangered avian species that was endemic to Texas, the Golden-cheeked Warbler. The University of Illinois provided this research connection in collaboration with the Fort Hood Military Installation, which holds one of the largest Golden-cheeked Warbler populations... Read More
Guest feature | Song dialects of the Ruby-crowned Kinglet
Many bird species, like humans, have distinct regional dialects. A New Yorker may refer to a midday meal as “lunch”, but in the south that meal is “dinner”. Likewise, the song of a Common Yellowthroat in the east may sound very different from one in the west... Read More
Guest feature | Cryptic migration in a common feeder bird shows it’s a great era for avian natural history
With all of the incredible revelations in ornithology during the 21st century, it’s easy for a young birder who wants to “discover new things about birds” to feel like they’re late to the scene. But upon getting deeper into field ornithology, it becomes readily apparent how much basic life history of North American birds remains […] Read More
Journal of Field Ornithology | The process of developing JFO into an Open Access journal
The new relationship between AFO and Resilience Alliance comes after a two year process to find a new publisher for the Journal of Field Ornithology. The publications landscape has changed considerably in the last decade with a number of intersecting trends. Academic libraries are reducing their publications budgets and increasingly seeking to purchase bundles and not individual subscriptions... Read More
Guest feature | Consequences and the strategy behind nest reuse in a Neotropical thrush
Have you ever seen a bird building its nest? The complex architecture of such structures is intriguing and lovely per se, but it is impossible not consider the hundreds, if not thousands, of trips carrying nesting material. A finished nest results from several days of parental effort aiming at providing adequate microclimate and protection to their offspring. It seems logical that all that energy... Read More
Guest feature | Nest-site selection by Cassia Crossbills and management implications
While gathering data on mate pairing patterns of Red Crossbills in the South Hills, Idaho for my dissertation, I occasionally found nests being built. Realizing that we knew so little about what eventually was described as the Cassia Crossbill, I decided to characterize nest locations. Trevor Fetz, another graduate student, was also conducting fieldwork on crossbills... Read More
Guest feature | Measuring the value of oil palm plantations versus native forest as habitat for Neotropical migratory birds in Mexico
I came to Michigan Technological University from southern Brazil in the Fall of 2017 to start my Ph.D. in the College of Forest Resources and Environmental Science. Once in Michigan, I was introduced to a diverse community of neotropical migrant songbirds that were rarely seen in my home country of Brazil. Although different species, I was familiar with some closely related South American birds within the same genus as those found in Michigan, such as warblers (Setophaga) and vireos (Vireo). Read More
Guest feature | Mid-summer arrival by Blue Grosbeaks at the northern extent of their breeding range: evidence for dual breeding?
On my morning running route through farmland with shrubby field borders in southeastern South Dakota, I noticed that Blue Grosbeaks often first showed up in the area on approximately July 1st. This arrival pattern seemed odd and different from arrival patterns of typical migrants in this habitat, such as Dickcissel, Indigo Bunting, Field Sparrow and Orchard Oriole... Read More- 2 of 3
