Welcome to the Missouri Turkey Vultures! This nest is located in the top of a barn in Marshall, Missouri.

The vultures have migrated south for the winter. We’ll turn the cam back on when they return.

About the Marshall Turkey Vultures

About the Turkey Vultures

The Marshall Turkey Vultures are nesting in an empty hay loft in a barn on private property near Marshall, MO. In general, vultures arrive in late March or early April and lay eggs in early May. Hatch begins about 28 days after the second egg is laid. Both parents incubate eggs and brood young.

Vultures eat primarily carrion. Although they prefer relatively fresh carrion, they are unable to tear carcasses open, which means they must wait until a carcass putrefies or is opened by mammals or larger vultures. This may be why they have been documented following bald eagles and black vultures.

Adult Turkey Vultures regurgitate food for their young, who fledge roughly sixty days after hatching. To learn more about turkey vultures in general, please follow this link to the Cornell Lab of Ornithology website.

Adults

Although vultures are classified as a member of the order  Accipitriformes, and so related to hawks, eagles, and falcons, males and female birds are similar in size and lack the strong feet and talons of most Accipitriforme birds. Turkey Vultures do not have a syrinx, so they grunt, stamp, and hiss instead of calling, singing, chattering, or otherwise making vocalizations that we associate with birds.

Nests

Turkey vultures lay eggs in dark, quiet recesses, including rock outcrops, mammal burrows, hollow logs, thickets, hollow trees, abandoned stick nests, and abandoned buildings. Nest sites must be dark and isolated from human disturbance.

Eaglet Growth and Development: Week Four

We’re writing a series of blogs about the first few weeks of an eaglet’s life. An eaglet spends roughly 75 to 80 days in the nest. For about the first half, it grows and gains weight. For about the second half, it grows flight feathers and starts developing the skills it will need post-fledge. We will focus on week four in this blog. During week three (fourteen to twenty-one days), the dynamic duo shed most of their natal down, gained

2024: 0629-44094, aka Ma FSV. She is 22 years old and fledged from a still active nest about 45 miles east of this one.

Bald Eagles, Menopause, and Ova

Do bald eagles go through menopause? Probably not, since we’ve documented menopause or prolonged post-reproductive lifespans in just four species.

Feather Follicle

What are feathers? What is molt?

Eaglets go through two molts and three feather stages in the nest: natal down (and molt), followed by thermal down (and molt), followed by juvenile feathers. As of this blog, the Decorah North eaglets are shedding the very last of their natal down and their thermal down is rapidly being replaced by juvenile down and feathers. We thought we would blog a little more about feathers to celebrate!  When we think about feathers, we tend to think about their qualities

Canada Geese: Precocial versus Altricial

As watchers know, Canada geese are nesting in two abandoned bald eagle nests in Decorah, Iowa. N2B – currently a goose nest – is located about 700 feet east of N1, where geese started hatching yesterday. This blog discusses some of the differences between altricial eagles and precocial geese!  Altricial eaglets rely on parental care until they fledge. But goslings are precocial: capable of moving around, self-feeding, and leaving the nest shortly after hatch. What does that mean? Read on

Eaglet Growth and Development: Week Three

We’re writing a series of blogs about the first few weeks of an eaglet’s life. An eaglet spends roughly 75 to 80 days in the nest. For about the first half, it grows and gains weight. For about the second half, it grows flight feathers and starts developing the skills it will need post-fledge. We will focus on week three in this blog. DN17 and DN18 turned 15 and 14 days old today. During week two (seven to 14 days),

September 7, 2024: Welcome Home, Norths!

The Norths appear to have accepted the nest we built for them – we saw them last night and early this morning! That makes us five for five: we rebuilt N2 in 2015 (Mom and Dad until 2018, Mom and DM2 until fall of 2020), DNN in 2018 (Mr. North and new mate DNF), Fort St. Vrain in 2020 (Ma and Pa FSV), N1 in 2021 (HM and HD), and DNN (again) this fall. If you’d like to know how

Attaching another brace to expand the nest and prevent slumping. John's first bionic limb rebuild out at Xcel Energy's Fort St. Vrain nest happened after the nest slumped.

Decorah North Nest Rebuild

We completed the Decorah North nest rebuild, cleaned the cameras, and are (mostly) on to our next project on the Mississippi Flyway. I’ve posted a few pictures so you can get a look at how we rebuilt the North nest. Spoiler alert: we used a bionic John-built limb to support a nest ‘basket’, which we filled with branches and mulch. We left two lovely trout for Mr. North and DNF! Click on the photos to enlarge them and see how

August 26, 2024: A quick update from all around our nests!

We’ve got a quick update from all around our nests! We’ve seen DNF and a juvenile – DN17 or DN18, perhaps? – around the Valley of the Norths, although neither DNF nor Mr. North have visited the nest we built for them yet. We’re not too worried about it, since the Norths don’t typically begin nestorations until October. But we do wish the mice hadn’t taken our housewarming gifts…those trout weren’t for you, mice! Given the amount of free food

July 30, 2024: Last Decorah North Chat of the 2023/2024 Season and NestFlix!

Even with the North nest falling, it was a great year for Norths! Come join us for the last chat of the 2023/2024 season on Friday, August 2, from 3:30 to 5PM: https://www.raptorresource.org/birdcams/decorah-north-nest/. We’ll be celebrating DN17 and DN18, reliving the year, and chatting about our plans! While the Norths and Hatchery Eagles are in the ebb of their year, we’re still seeing both couples in and around their nesting areas, including a thrilling visit by HD on July 26.

July 18, 2024: A last glimpse of DN17

July 25, 2024: Are DN17 and DN18 on walkabout?

Have DN17 and DN18 started walkabout? Although our camera operators have been looking, we haven’t seen DN17 since July 18th – just as we were gathering for ATF – and DN18 since July 20. While the Decorah nestlings we attached transmitters to didn’t tend to disperse until early September, they started wandering more widely about 30 days post-fledge and began spending more nights away from home. We’ll keep looking for them, since it wasn’t uncommon for our wanderers to return
