How Just a Few Acres of Ideal Habitat Helped Protect Henslow鈥檚 Sparrows

Quick action and a partnership with a local winery allowed the Central Kentucky 爆料公社 Society to protect a local population of Henslow鈥檚 Sparrows鈥攁nd led to a discovery that could help the species in other places.

One summer day in 2020, Katey Buster decided to bird at a local Kentucky winery in hopes of adding a Henslow鈥檚 Sparrow to one of her eBird county life lists. Little did she know that her birding excursion would lead to a new discovery about the species.

That day Buster, a member of the , only expected to hear or see a couple Henslow鈥檚 Sparrows鈥攐ne of , as labeled by the Kentucky Department of Fish and Wildlife鈥攁t Talon Winery. Instead, she was greeted with approximately six of them darting amid the area鈥檚 grasses, an uncommon sight in Lexington, Kentucky. 

鈥淚 was so excited, but then, I heard the roar of a tractor motor,鈥 says Buster. 鈥淪o I looked around and saw that [the winery] was getting ready to mow.鈥

She launched into action and called winery staff in hopes of persuading them to save some acreage for these songbirds. Since they were aware of the chapter鈥檚 mission to protect birds, they were more than willing to help. Later that day, Buster, Tony Brusate, the president of the chapter, and David Lang, the vice president, staked off five acres of land that surrounded the sparrows, hoping that it would be enough for them to breed.

But once the team started to learn more about this species, they realized that there was a problem: previous research concluded that Henslow鈥檚 Sparrows needed far more land to nest. In fact, several studies showed that the sparrows require at least to in order to successfully raise their brood.

鈥淸Our staked acreage] was considerably less than any of the research we looked at,鈥 says Brusate. 鈥淓verything said this shouldn鈥檛 work. If I had known that first, I don鈥檛 know if that would have deterred me, but we had everything set up, and we said that we鈥檇 try it.鈥

To their surprise, the Henslow鈥檚 Sparrows made their nesting homes within the five allotted acres and stayed for the entire breeding season.

Chapter members continued to monitor the birds throughout the season to make sure that they were indeed raising young. Lang spent the hot summer days in a bird blind photographing them to confirm that the adults were bringing back food to the nests and carrying out fecal sacs, both key signs that the sparrows had successfully bred. 

Even the Kentucky eBird community joined in the observation process as photographers from far and wide visited the winery to photograph the adults and, later, the fledged young.

Once the last of the Henslow鈥檚 Sparrows had left for the season, the team realized what a significant discovery they made. Brusate on protecting the sparrows to the Kentucky Ornithological Society鈥檚 peer-reviewed journal, the , for others to discover and replicate elsewhere.

鈥淧ublishing this report was important because it鈥檚 something to use with people or businesses with large amounts of acreage,鈥 says Ronan O'Carra, a chapter board member and editor of the Kentucky Warbler. 鈥淭hey may not be willing to give a huge amount of land, but even five acres would be enough.鈥

It turned out that the 2020 breeding season was not a unique occurrence for the sparrows. The next year, the songbirds returned to Talon Winery鈥檚 grasses and, with five acres once again staked off, produced two broods that season. This year, chapter members are continuing to collaborate with the winery to prepare the sparrows鈥 five-acre summer home.

Looking back, members reflected on the efforts it took to save these sparrows. One key factor was being able to work with Talon Winery鈥攁 partnership they鈥檙e thankful for, since they faced obstacles in the past working with other businesses to save bird habitat.

鈥淚 was surprised that this worked,鈥 says Brusate. 鈥淚t takes people willing to say, 鈥榯hat鈥檚 where the birds are鈥攍et鈥檚 give them some space.鈥 It also takes people who own the property to be willing to do that.鈥

Of course, the most important piece of this conservation success story was actually finding where the birds were, as Buster did on that summer day.

鈥淸The Henslow鈥檚 Sparrows] already picked the ideal habitat, and we just saved five acres of it from getting hayed,鈥 says Brusate. 鈥淪omehow that made all the difference.鈥
