Oradell Animal Hospital is privileged to be the spring home of cliff swallows (a species of special concern in NJ). There are only a few breeding nests in the state. They have returned from their winter home in South America, for the third straight year, to build their gourd shaped mud nests by the main entrance and side exit doors. They are colorful small acrobatic insectivores. So on your next visit to Oradell Animal Hospital, look up and enjoy these special birds.
