One of the Amazon River's main tributaries has dropped to its lowest level ever recorded, Brazil's geological service said Friday, reflecting a severe drought that has devastated the Amazon rainforest and other parts of the country.

The level of the Negro River at the port of Manaus was at 12.66 meters on Friday, as compared with a normal level of about 21 meters. It is the lowest since measurements started 122 years ago.

The previous record low level was recorded last year, but toward the end of October.

The Negro River's water level might drop even more in coming weeks based on forecasts for low rainfall in upstream regions, according to the geological service's predictions.

Andre Martinelli, the agency's hydrology manager in Manaus, was quoted as saying the river was expected to continue receding until the end of the month.

Water levels in Brazil's Amazon always rise and fall with its rainy and dry seasons, but the dry portion of this year has been much worse than usual.

All of the major rivers in the Amazon basin are at critical levels, including the Madeira River, the Amazon River's longest tributary.

The Negro River drains about 10% of the Amazon basin and is the world's sixth-largest by water volume. Manaus, the biggest city in the rainforest, is where the Negro joins the Amazon River.

For locals, the drought has made basic daily activities impossible. Gracita Barbosa, 28, works as a cashier on a floating shop on the Negro River.

She's out of work because boats that once stopped there can no longer navigate the river due to the low water levels.

Barbosa can no longer bathe in the river and now has to travel longer distances to collect drinking water.

More than a dozen tigers were incinerated after the animals contracted bird flu at a zoo in southern Vietnam, officials said.
State media VNExpress cited a caretaker at Vuon Xoai zoo in Bien Hoa city saying the animals were fed with raw chicken bought from nearby farms, The Associated Press reported. The panther and 20 tigers, including several cubs, weighed between 10 and 120 kilograms when they died. The bodies were incinerated and buried on the premises.
“The tigers died so fast. They looked weak, refused to eat and died after two days of falling sick,” said zoo manager Nguyen Ba Phuc.
Samples taken from the tigers tested positive for H5N1, the virus that causes bird flu.
The virus was first identified in 1959 and grew into a widespread and highly lethal menace to migratory birds and domesticated poultry. It has since evolved, and in recent years H5N1 was detected in a growing number of animals ranging from dogs and cats to sea lions and polar bears.
In cats, scientists have found the virus attacking the brain, damaging and clotting blood vessels and causing seizures and death.
More than 20 other tigers were isolated for monitoring. The zoo houses some 3,000 other animals including lions, bears, rhinos, hippos and giraffes.
The 30 staff members who were taking care of the tigers tested negative for bird flu and were in normal health condition, VNExpress reported. Another outbreak also occurred at a zoo in nearby Long An province, where 27 tigers and 3 lions died within a week in September, the newspaper said.
Unusual flu strains that come from animals are occasionally found in people. Health officials in the United States said Thursday that two dairy workers in California were infected — making 16 total cases detected in the country in 2024.
“The deaths of 47 tigers, three lions, and a panther at My Quynh Safari and Vuon Xoai Zoo amid Vietnam’s bird flu outbreak are tragic and highlight the risks of keeping wild animals in captivity,” PETA Senior Vice President Jason Baker said in a statement sent to The Associated Press.
“The exploitation of wild animals also puts global human health at risk by increasing the likelihood of another pandemic,” Baker said.
Bird flu has caused hundreds of deaths around the world, the vast majority of them involving direct contact between people and infected birds.
