"...This was the first targeted dual-polarization radar, multiple-Doppler, and micronet study of the impacts of totality on meteorology and insect behavior...Rapid and substantial changes in the boundary layer and propagation of a prominent radar fine line associated with a posttotality wind shift mechanism different than previously hypothesized were observed. Profound and rapid changes in airborne insect behavior were documented, including descent and then reascent during the minutes immediately surrounding totality, with implications related to solar-related insect navigational mechanisms and behavior."

AMETSOC · Atmospheric and Insect Responses to a Total Solar EclipseAbstract How do the atmosphere and airborne insects respond to the abrupt cessation and restoration of sunlight during a total eclipse? The Flexible Array of Radars and Mesonets (FARM), including three mobile Doppler on Wheels (DOW) radars, mobile mesonets, Pod weather stations, and an upper-air sounding system, was deployed as an unprecedentedly dense observing network in the path of totality of the 21 August 2017 eclipse that spanned the United States from its Pacific to Atlantic coasts. This was the first targeted dual-polarization radar, multiple-Doppler, and micronet study of the impacts of totality on meteorology and insect behavior. The study area was chosen to be completely sunny, nearly devoid of trees, with homogeneous, nonforested land use, and very flat. This resulted in as near an ideal observational environment as realistically attainable to observe the effects of a total solar eclipse absent the confounding effects of variable cloud shading, terrain, and land use. Rapid and substantial changes in the boundary layer and propagation of a prominent radar fine line associated with a posttotality wind shift mechanism different than previously hypothesized were observed. Profound and rapid changes in airborne insect behavior were documented, including descent and then reascent during the minutes immediately surrounding totality, with implications related to solar-related insect navigational mechanisms and behavior.

Continental-scale behavioral response of birds to a total solar eclipse: nature.com/articles/s41598-025 -> Eclipse echoes - groundbreaking study reveals surprising avian vocal patterns during solar eclipse: eurekalert.org/news-releases/1 -> The epic total #SolarEclipse of 2024 caused some birds to stop singing: space.com/stargazing/eclipses/

NatureContinental-scale behavioral response of birds to a total solar eclipse - Scientific ReportsBased on anecdotal evidence and research involving human observation and community science, radar analyses, and acoustical studies, birds are thought to stop singing and engage in nighttime behaviors such as roosting during a total solar eclipse. However, these research methodologies are limited by small sample sizes, potential effects of human observation altering birds’ behaviors, and biases in human-recorded findings. Here we show how a community science network of bioacoustics devices using machine learning revealed a decrease in bird vocalization across North America at sites which experienced more than 99% maximum solar obscuration during the total solar eclipse on April 8, 2024. There was variability between sites in bird vocalization responses to a solar eclipse after controlling for human presence. A widely distributed, connected, and automated passive acoustics monitoring system will allow research into the impact on wildlife of wide spatiotemporal, continental-scale events including wildfires and extreme weather events.

One year ago today I watched the #SolarEclipse in Arkansas. The two total eclipses I've seen have been magnificent to a level that is difficult to describe to those who haven't seen totality.

Here's our photos, experience, and the #weather data I recorded.
