The Value of Acoustic Technologies for Monitoring Bird Migration
The value of acoustic technologies for monitoring bird migration Andrew Farnsworth, Conservation Science Program Monitoring using acoustic technologies 1) Informing traditional auditory monitoring 2) Monitoring species that are difficult to survey. 3) Monitoring migrants by recording flight-calls. Many species produce flight calls: unique vocalizations, varying in frequency, duration, and pattern; primarily given in sustained flight, presumably for communication. Dickcissel Black-billed Cuckoo Red-breasted Nuthatch Bobolink White-throated Sparrow Swainson’s Thrush Evans and O’Brien (2002) Recording flight calls: nocturnal Recording flight calls: diurnal Recording flight calls: captive birds Designed by M. Lanzone (Lanzone and Farnsworth submitted) Recording Type Projects: Captive Free-flying Offshore Recording Locations DoD Sites American Redstart Raven birds.cornell.edu/Raven XBAT www.xbat.org Traditional analysis Syllabic measurements Modulation Sweep Spectral and temporal measurements BBWA_fig Maximum Bandwidth Minimum Duration New ways of representing flight-calls • Spectrogram Cross Correlation – acoustic (particularly “syllabic”) similarity among species – identify flight-call “template” for each species that best correlates with remaining calls • ACOUSTAT/XBAT – treat spectrogram data as probability distributions – characterize using order statistics (e.g. median) K. Cortopassi Swainson’s Thrush variation • Learn the variation in a species you hear often • Note the differences in trailing modulation, duration, and initial upsweep in these calls Low frequency, thrush-like calls BITH GCTH HETH SWTH VEER WOTH BAOR BUOR OROR RHWO BOBO WEME EAME MOBL EABL • These calls exhibit a wide array of frequencies, degrees of modulation, sweeps, and shapes. However, when heard in passing, these identifications can be challenging. “Zeep” Complex Blackburnian Blackpoll Cerulean Connecticut Louisiana Waterthrush Magnolia Worm-eating Yellow • Similarity in duration and “shape” for all of these species; slight differences in frequency ranges, degree and depth of modulation. -

HUTTO Department of Zoology, Universityof Montana, Missoula, MT 59812 Abstract. Insectivorousbird flockswere observed in all typesof forestedhabitats during the nonbreedingseason in westernMexico. The speciescomposition of flockschanged markedlyand predictablyamong five categoriesof habitat type. The averagenumber of speciesper flockin lowlandhabitats was 4.7, while a mean of 18.6 speciesparticipated in highlandflocks, ranking the latter amongthe most species-richflocks in the world. The meanproportion of the localinsectivorous species that participatedin mixed-speciesflocks wassignificantly greater in the highlands(6 1.3%)than in the lowlands(24.6%). About half of the flock participantsin both undisturbedlowland and highlandhabitats were north temperatemigrants, ranking west Mexican flocks among the mostmigrant-rich in the world as well. In highlandflocks, the maximum numberof individualsper attendantspecies was generallytwo to three,but therewere often six to twelveindividuals belonging to eachof severalnuclear species.

Avian upsloping in the tropics: Myioborus miniatus and Myioborus torquatus abundance in different altitudinal ranges in Boquete, Chiriquí, Panama Julie Yoon University of Kentucky SIT Panama: Tropical Ecology, Marine Ecosystems, and Biodiversity Conservation Spring 2019 2 Abstract Direct and indirect effects of warming global temperatures due to climate change are known to cause upwards shifts of the altitudinal ranges of some avian species. Most susceptible to this trend and at risk of riding the “escalator to extinction” are endemic species in tropical montane cloud forests, such as Myioborus torquatus. There are abiotic factors, like temperature, and biotic interactions, such as the presence of its altitudinal neighbor Myioborus miniatus, that limit the altitudinal range of this bird species in the Neotropics. -
Ecology, Morphology, and Behavior in the New World Wood Warblers
Ecology, Morphology, and Behavior in the New World Wood Warblers A dissertation presented to the faculty of the College of Arts and Sciences of Ohio University In partial fulfillment of the requirements for the degree Doctor of Philosophy Brandan L. Gray August 2019 © 2019 Brandan L. Gray. All Rights Reserved. 2 This dissertation titled Ecology, Morphology, and Behavior in the New World Wood Warblers by BRANDAN L. GRAY has been approved for the Department of Biological Sciences and the College of Arts and Sciences by Donald B. Miles Professor of Biological Sciences Florenz Plassmann Dean, College of Arts and Sciences 3 ABSTRACT GRAY, BRANDAN L., Ph.D., August 2019, Biological Sciences Ecology, Morphology, and Behavior in the New World Wood Warblers Director of Dissertation: Donald B. Miles In a rapidly changing world, species are faced with habitat alteration, changing climate and weather patterns, changing community interactions, novel resources, novel dangers, and a host of other natural and anthropogenic challenges. Conservationists endeavor to understand how changing ecology will impact local populations and local communities so efforts and funds can be allocated to those taxa/ecosystems exhibiting the greatest need. Ecological morphological and functional morphological research form the foundation of our understanding of selection-driven morphological evolution. Studies which identify and describe ecomorphological or functional morphological relationships will improve our fundamental understanding of how taxa respond to ecological selective pressures and will improve our ability to identify and conserve those aspects of nature unable to cope with rapid change. The New World wood warblers (family Parulidae) exhibit extensive taxonomic, behavioral, ecological, and morphological variation. -
Colombia Trip Report Santa Marta Extension 25Th to 30Th November 2014 (6 Days)
RBT Colombia: Santa Marta Extension Trip Report - 2014 1 Colombia Trip Report Santa Marta Extension 25th to 30th November 2014 (6 days) Buffy Hummingbird by Clayton Burne Trip report compiled by tour leader: Clayton Burne RBT Colombia: Santa Marta Extension Trip Report - 2014 2 Our Santa Marta extension got off to a flying start with some unexpected birding on the first afternoon. Having arrived in Barranquilla earlier than expected, we wasted no time and headed out to the nearby Universidad del Norte – one of the best places to open our Endemics account. It took only a few minutes to find Chestnut- winged Chachalaca, and only a few more to obtain excellent views of a number of these typically localised birds. A fabulous welcome meal was then had on the 26th floor of our city skyscraper hotel! An early start the next day saw us leaving the city of Barranquilla for the nearby scrub of Caño Clarín. Our account opened quickly with a female Sapphire-throated Hummingbird followed by many Russet-throated Puffbirds. A Chestnut-winged Chachalaca by Clayton Burne White-tailed Nightjar was the surprise find of the morning. We added a number of typical species for the area including Caribbean Hornero, Scaled Dove, Green-and-rufous, Green and Ringed Kingfishers, Red-crowned, Red-rumped and Spot-breasted Woodpeckers, Stripe-backed and Bicolored Wrens, as well as Black-crested Antshrike. Having cleared up the common stuff, we headed off to Isla de Salamanca, a mangrove reserve that plays host to another very scarce endemic, the Sapphire-bellied Hummingbird. More good luck meant that the very first bird we saw after climbing out of the vehicle was the targeted bird itself. -

FIELD GUIDES BIRDING TOURS: Colombia: Bogota, the Magdalena
Field Guides Tour Report Colombia: Bogota, the Magdalena Valley, and Santa Marta 2014 Jan 11, 2014 to Jan 27, 2014 Jesse Fagan & Trevor Ellery For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. A fun group and the most productive tour we have had to date! We observed 582 bird taxa in 17 days of birding, which beat our record last year of 555 by a bunch. As we fine-tune our birding route and learn more about Colombian birds things just seem to get better and better. This year we saw 33 endemics and loads of interesting subspecies and near-endemics. Highlights included a female Blue- billed Curassow, Kelp Gull(s) at Los Camerones (only the second time it has been recorded in Colombia), Dwarf and Pavonine cuckoos (the latter a lifer for Trevor!), a splendid Crested Owl, Sapphire- bellied Hummingbird (nice comparisons with Sapphire-throated), Double-banded Graytail in the coffee finca below Reinita Cielo Azul lodge, the always elusive Santa Marta Bush-Tyrant and antpitta, Turquoise Dacnis, and singing Yellow-bellied Siskin. It is really hard to pick just one from so many! I want to thank all of you again for a really enjoyable trip. Thanks also to Trevor Ellery, our local guide, and Giovanni, our driver, for their hard work. I look forward to seeing you again in the field. Bird On. --Jesse a.k.a.
