Hospital staff arranged a special visit for bird lover Cleve after he spent five months intensive care.
The hatching of hen harrier chicks at nests on a private estate for the second year running "gives hope for the future", the RSPB has said.
The charity said it found the hatchlings in four nests on the Bowland Estate in Lancashire's Ribble Valley.
Project officer James Bray said as hen harriers were in severe decline, the birds had been "closely" monitored.
The total number of chicks was unknown, but it was hoped there would be more than the 13 born in 2018, he added.
