In March 2006, the Maryland Zoo announced it would be accepting three female African elephants from the Philadelphia Zoo in Pennsylvania as part of the expanded elephant exhibit, but construction was then indefinitely delayed and later the elephant loan was canceled. However, two new elephants came to the Maryland Zoo from Arkansas in 2007. On March 19, 2008, "Felix," one of the Zoo's female elephants, gave birth to a 290-pound male calf, the first elephant born in the Zoo's history. The baby is named "Samson" and he is currently 14 years old. In the spring of 2010, the Zoo's warthogs had two male offspring, which were viewable beginning in May of that year. In February 2017, the first giraffe calf was born at the Zoo in over 20 years. Willow was born to parents Juma and Caesar, and was 6'1", and 125 lbs at birth. In March 2018, the zoo announced plans to expand the zoo's elephant, giraffe and lion exhibits. This $20 million project was made to improve living standards for the animals and also to give a much better viewing experience for guests of the Maryland zoo. The details of this initiative included the expansion of the Elephant habitat from 0.92 acres (0.37 ha) to 2.1 acres (0.85 ha), the expansion of the Giraffe habitat by 33%, the removal of what used to be "Rock Island" and several new viewing areas for the lions. The renovations finished in the Summer of 2019. On December 29, 2019, the Zoo welcomed a baby chimpanzee after an 8 month gestation period.
