Three osprey chicks hatch in 500-pound steel nest boxes
Operation Osprey is officially a success. Three osprey chicks are now sitting high atop the Bear Mountain Bridge overlooking the scenic and sturgeon-stocked Hudson River in New York's Hudson Valley.
These three new chicks were born in a nest constructed just for them with the help of some humans from the New York State Bridge Authority. The steel nesting boxes were installed this year to keep the birds, eggs, and motorists safe and allow the osprey to stay in their preferred nesting spot on top of the bridge.
'We noticed that two years ago at the Bear Mountain Bridge, [that] they started building nests on top of the tower,' Craig Gardner, manager of maintenance for the New York State Bridge Authority, told Popular Science in April. 'It's not really an ideal spot for us, so we would go up and try to encourage them to go someplace else. But then last year, before we could get the nest, they laid eggs. So then we stayed away from the nest.'
Roughly 20,000 vehicles cross the Bear Mountain Bridge every day and the osprey nests themselves are about 250 feet high, so any falling debris can cause car accidents. Bridge Authority workers typically try to encourage birds to nest on the lower spans, closer to the river and away from cars. But these birds wouldn't budge and appear to really like their perch high above the New York fjord.
In 2024, the osprey clutch successfully hatched and the chicks remained in the nest for most of the year. For this year, safety concerns prompted the team at the Bridge Authority to build the special steel boxes to keep the residents of any nests built this year safe.
'We took it up in components and assembled it on the top of the tower,' says Gardner. 'They [the birds] were back there as soon as we left, rearranging the sticks and establishing their nest.'
When all weighed together, the engineers took about 500 pounds of steel 350 feet in the air to install the nest boxes. The chicks are expected to remain there for several months.

Thanks to ongoing conservation efforts in the Hudson River and the surrounding area, bald eagles, peregrine falcons, ospreys–and the fish that they need to survive–have seen a major recovery. The osprey are also the second most widely distributed raptor species, after the peregrine falcon, which can also nest on the bridges.

Measles vaccination rates drop after COVID-19 pandemic in counties across the US
'When you look at the state level or national level ... you really don't see those drastic drops. Those are there. They're real and they're really problematic,' said Lauren Gardner, an expert in infectious disease modeling at Johns Hopkins University who is the paper's senior author. Gardner also built the university's COVID-19 database. Most of the measles cases in the U.S. this year — 1,088 nationally as of Friday — are in unvaccinated people. It has been spreading among communities due to international and domestic travel. Three people have died from measles during this year's outbreaks, and 2025 is inching closer to becoming the worst for measles in more than three decades. Get Starting Point A guide through the most important stories of the morning, delivered Monday through Friday. Enter Email Sign Up Measles was eliminated in the U.S. in 2000, and the vaccine is safe and highly effective. Public schools nationwide require two doses of the measles, mumps and rubella vaccine before kindergarten, but the number of children with non-medical exemptions from those requirements hit an all-time high in the 2023-2024 school year. Health experts say community-level vaccination needs to be at 95% or higher to prevent outbreaks. Advertisement The Johns Hopkins study looked at 2,066 counties across 33 states, comparing kindergarten vaccination rates averaged over school years from 2017-2020 to averages from 2022-2024. Where kindergarten data wasn't available, the researchers used a comparable rate. Advertisement Here's what it looks like in counties where there have been outbreaks this year, including in Texas counties that are the epicenter of measles. Texas Texas has logged 742 measles cases since late January, most in West Texas. Gaines County has 411 cases, the most in the state. Almost 2% of its population got measles. While the county saw a two percentage-point increase in vaccination rates after the pandemic, its 82.4% rate remains below herd immunity. Terry County (60 cases) and Yoakum County (20 cases) dropped below the 95% threshold for herd immunity after the pandemic, to 93.7% and 91.8% respectively. Lubbock County — which has seen 53 cases and is the closest metro area to Gaines County — was just below 95% before the pandemic, but dropped three percentage points after to 91.8%. El Paso County on the border of Mexico has had the third-most measles cases in Texas this year with 57. Its vaccination rate is higher than 95% but saw a 2.1 percentage-point decline to 96.5%. Kansas Counties with outbreaks in Kansas include Gray with 25 cases, Haskell with 11 and and Stevens with seven. Vaccination rates in Gray County dropped 23 percentage points after the pandemic, from 94% to 71%. Haskell County dropped 18 percentage points to 65%. And Stevens County dropped 0.5 percentage points to 90.5%. Colorado Colorado's outbreak, which is linked to an international flight that landed at the Denver airport in mid-May, involves six cases: five in state residents and one out-of-state traveler. Two people who got measles live in Arapahoe County in the Denver metro, where the vaccination rate dropped 3.5 percentage points to 88.4%. Three others live in El Paso County, home to Colorado Springs, where the vaccination rate dropped 3.8 percentage points to 80% post-pandemic. Advertisement North Dakota Pre-pandemic data in North Dakota wasn't available to Johns Hopkins researchers, but they looked at rates from school years ending in 2022, 2023 and 2024. North Dakota's first outbreak started in Williams County, which now has 16 measles cases. In the timeframe researchers looked at, vaccination rates in Williams rose from 84.6% in 2022 to 87.7% in 2023, only to drop back to 83.5% in 2024. Cass County has seven cases, and its rate has stayed steady at about 92.7%, while Grand Forks County, which has 10 measles cases, dropped from 95.4% to 93.4%.

Measles vaccination rates drop after COVID-19 pandemic in counties across the US
Childhood vaccination rates against measles fell in the years after the COVID-19 pandemic in nearly 80% of the more than 2,000 U.S. counties with available data — including in states that are battling outbreaks this year. A Johns Hopkins University study, published in JAMA this week, illustrates where more vulnerable communities are located. The results mirror trends established at state and national levels: Routine childhood vaccination rates are dropping. 'When you look at the state level or national level … you really don't see those drastic drops. Those are there.
