 The 𝐰𝐡𝐢𝐬𝐤𝐞𝐫𝐞𝐝 𝐭𝐞𝐫𝐧 (𝐂𝐡𝐥𝐢𝐝𝐨𝐧𝐢𝐚𝐬 𝐡𝐲𝐛𝐫𝐢𝐝𝐚) is a species of tern in the 𝐟𝐚𝐦𝐢𝐥𝐲 𝐋𝐚𝐫𝐢𝐝𝐚𝐞. The 𝐬𝐩𝐞𝐜𝐢𝐟𝐢𝐜 𝐧𝐚𝐦𝐞 𝐡𝐲𝐛𝐫𝐢𝐝𝐮𝐬 is 𝐋𝐚𝐭𝐢𝐧 for 𝐡𝐲𝐛𝐫𝐢𝐝; 𝐏𝐞𝐭𝐞𝐫 𝐒𝐢𝐦𝐨𝐧 𝐏𝐚𝐥𝐥𝐚𝐬 thought it might be a hybrid of 𝐰𝐡𝐢𝐭𝐞-𝐰𝐢𝐧𝐠𝐞𝐝 𝐛𝐥𝐚𝐜𝐤 𝐭𝐞𝐫𝐧 and 𝐜𝐨𝐦𝐦𝐨𝐧 𝐭𝐞𝐫𝐧.

The 𝐬𝐮𝐦𝐦𝐞𝐫 𝐚𝐝𝐮𝐥𝐭 has 𝐰𝐡𝐢𝐭𝐞 𝐜𝐡𝐞𝐞𝐤𝐬 and 𝐫𝐞𝐝 𝐥𝐞𝐠𝐬 and 𝐛𝐢𝐥𝐥.In 𝐰𝐢𝐧𝐭𝐞𝐫, the 𝐟𝐨𝐫𝐞𝐡𝐞𝐚𝐝 becomes 𝐰𝐡𝐢𝐭𝐞 and the 𝐛𝐨𝐝𝐲 𝐩𝐥𝐮𝐦𝐚𝐠𝐞 a much 𝐩𝐚𝐥𝐞𝐫 𝐠𝐫𝐞𝐲.
