We live in an incredibly well-lit world. All that wattage in heavily-populated areas creates a halo glow that brightens the night sky. Researchers at the Cornell Lab of Ornithology, Syracuse University, and Globe at Night are seeking participants for a unique new study. Scientists want to know what impact all that extra night light might have on the circadian rhythms of life using Barn Swallows as their subjects. Barn Swallows have adapted to live near humans and nest almost exclusively on structures such as bridges, homes, and yes, barns. Volunteers can sign up through NestWatch.
“Specifically, we’re hoping to learn if the artificial light has an effect—good or bad—on what we call the ‘pace of life,’” says Cornell Lab of Ornithology researcher Caren Cooper. “It’s been established that creatures that live in areas where daytime is shorter during breeding, such as the tropics, have a lower metabolism and a longer life span. On the flip side, animals that breed where there is more daylight tend to have a faster metabolism and shorter life. Is the pace of life for Barn Swallows increasing if they live in areas where the days seem even longer due to artificial lights?”
“Previous studies have shown that birds living in areas with artificial light at night start singing well before dawn, start eating earlier, eat more during the day, and have more complex social interactions,” says researcher Margaret Voss at Syracuse University. “Expanding those activities takes its toll in energy use. We want to learn how that might play out when it comes to health and survival as the Barn Swallows build nests and raise their chicks.”
Did you know that NestWatch can accept historic data going back all the way to 1900? If you have old notebooks or data sheets full of nesting observations just sitting around gathering dust, why not enter them into NestWatch?
Now, more than ever, we need baseline data with which to compare modern nesting behavior. In this time of changing climate and habitat, you can give new relevance to forgotten data by adding it to our permanent collection of nest monitoring records.
How do you enter old data? The same way you enter modern data! Data should be similar to that currently collected by NestWatch. That means you need, at a minimum, a location, a species, and preferably an outcome (although unknown nest fates are accepted). Number of eggs, chicks, and fledglings, along with first-egg dates, will be particularly helpful. Simply enter the data as you normally would, using our online system. NestWatch may ask for information that you don’t have (for example, time of day the nest was visited) but do the best you can, realizing that data are still valuable even if some fields are missing. If you have hundreds of old nest records, ask about our Bulk Import Tool. As always, contact us if you have questions about entering data, historic or current.
If you have a smartphone or tablet, you can use NestWatch in the field and skip the data sheets! NestWatch’s mobile-friendly data entry page responds to the size of your screen so it is always formatted for easy viewing.
Simply visit us on any of your mobile devices and submit data while at a nest site, and then bookmark NestWatch.org on your device to return whenever you check the nest again. All you need is an Internet connection and your smartphone or tablet to go paperless! Try it today.
It started as a curious observation: NestWatcher Gerald Clark noticed an oddly large egg among the clutch of four in the bluebird box he was monitoring last summer near his home in State College, Pennsylvania. When he went back to check the nest box in early July, there were five bluebird chicks—including two smaller-sized nestlings, which presumably came from the same egg. In other words, twins. Twinning is very rare in the bird world (fewer than half of 1% of waterfowl eggs in one study contained twins), but it’s never been observed in bluebirds before.
Clark’s find was so notable it was written up and published in the scientific journal PeerJ, in a paper co-authored by Clark and NestWatch project leader Robyn Bailey. The paper is available online, and Robyn will share more details about the story at the Bluebird Society of Pennsylvania Conference on March 29 in State College.
Welcome to our newest NestWatch Chapter, at Biodiversity Research Institute, located in Gorham, Maine! Maine is a new state for the NestWatch Chapters program. Biodiversity Research Institute monitors 42 nest boxes on the property and is planning to involve 4 middle schools in Maine in nest monitoring this year. Find a NestWatch Chapter near you.
