Lincoln Park Zoo is trumpeting its newest arrivals. 

Four cygnets -- aka baby trumpeter swans -- hatched at the zoo this week, and they're already making the pond their home. According to the zoo, the cygnets were born June 2 and 3, and are available for public viewing as they explore the water and land around the McCormick Swan Pond. 

Time is short to watch the younglings grow, however. The four cygnets are part of the zoo's collaboration with the Iowa Department of Natural Resources. Once the summer is over, they will be released back into the wild as part of the program. 

In that time, the cygnets are expected to triple in size as they learn to feed on seeds, grain, insects and small fish. Adult males can get as large as 30 pounds and have wingspans of 30 feet.
