墾丁地區為台灣秋季遷移猛禽的主要觀察地點，2004 年起墾丁國家公園管理處委 託台灣猛禽研究會投入調查。2008 年起增加春季調查後，也確認本區同樣是春季猛禽 遷移的重要路線。2012 年墾丁春季地面調查期間為03/06~05/05。將恆春半島分為3 區， 依據天候與猛禽過境狀況，至少由2 名調查員分區進行地面同步調查，每日調查時間 至少10 小時。記錄過境猛禽之時間、種類、數量、飛行方式等。結果本年春季共記錄 到2 科14 種遷移性猛禽，包括墾丁地區新記錄種白尾海鵰（Haliaeetus albicilla）。單種 數量以赤腹鷹（Accipiter soloensis）39,687 隻、灰面鵟鷹（Butastur indicus）22,410 隻最多， 均為此2 種於墾丁春季地面調查之新高紀錄。赤腹鷹的主要過境期為4/15~4/30，共16 日。紀錄時段以14:00~18:00 最多，佔本季族群量之70.7%，並觀察到多次登陸情形。 灰面鵟鷹的過境期自3/16~4/6 共22 日，亦高於歷年記錄；紀錄時段則以10:00~13:00 最多（39.5%）。紀錄地點方面，灰面鵟鷹以西海岸紀錄數量最多（48%）；赤腹鷹則 為東海岸（74.46%）。族群數量增加、過境路線的變動與天候狀況等，都可能造成本 季猛禽過境模式與與先前觀察結果略有不同。

Kenting National Park is the most important site for monitoring atumn raptor migration in Taiwan. RRGT was responsible for conducting this survey from 2004. Since 2008, the survey had expanded to include spring migration and found aboundant raptor populations passed in both seasons. The 2012 spring survey was conducted from March 6th through May 5th. On each day, at least 2 counters stationd at 2 different points surveyed simultaneously at least 10 hours. 14 species of migratory raptors were recored this season, including a White-tail Sea Eagle (Haliaeetus albicilla), which is the first record in this area. The most numberous 2 species were Chinese Goshawk (Accipiter soloensis) and Grey-faced Buzzard (Butastur indicus), with total numbers of 36,570 and 10,542 respectively. 90% of Grey faced-Buzzards passed between March 16th and April 6th, within a period of 22 days. 90% of Chinese Goshawks passed in 16 days, which was from April 15th to April 30th. Daily peak passage hours for Grey-faced Buzzards were from 10:00 to 13:00, and more than 70% of Chinese Goshawks were recorded between 14:00 to 18:00. Population numbers were varied between sites, 48.4% of Gray-faced Buzzards were recorded in the west coast and 74.5% of Chinese Goshawks in the east. However, Population numbers in each areas, daily peaks and passage periods of raptors were various between years, which may relate to population size or the weather conditions during ocean-crossing flight.
