A baby swan that was rescued from its home on the Charles River Esplanade after having difficulty swimming earlier this month died in a rehabilitation facility, officials said.
The cygnet was rescued by a Boston Animal Control officer on June 1, after Boston 311 received a report of an “injured/sick” swan, the Globe reported. The rescue came just one day after the swan’s mother died of unidentified causes. The cygnets were hatched beginning on May 24.
When it was rescued, the cygnet was taken to a “reputable wildlife rehabber” on the South Shore, the Boston Parks and Recreation Department said in a statement. After days of improving condition, plans were made for returning the cygnet to its home in the Storrow Lagoon. Then the cygnet “took an unexpected downturn” while at the rehab facility and died last week.
US Department of Agriculture studies found that the mortality rate for cygnets is estimated at 60 percent to 70 percent.
Sylvia Zarco, a self-described “wildlife person” who has been documenting the swans’ journey on Instagram, reported earlier this week that another of the cygnets had been killed by a snapping turtle.
Zarco, who told the Globe earlier this month that she visits the swan family daily, has since documented just three cygnets with their father.
