The parasites of indigenous populations of mourning doves (Zenaida macroura) in north and south Florida were compared with those of an introduced population of white-winged doves (z. asiatica) in south Florida. Thirty-two species of parasites including 5 protozoans, 7 nematodes, 2 trematodes, 2 cestodes, 7 acarines, 7 mallophagans, and 2 dipterans were found. Of these, 16 common to both species of doves. Mourning doves from north Florida showed a more diverse parasite fauna than did the white-winged or mourning dove populations from south Florida. Nematodes were the most common parasites in all three populations; infected doves contained one or two nematode species per dove. Total helminth burdens per infected dove averaged 13.1 for white-winged doves, 19.9 for mourning doves in south Florida, and 6.6 for mourning doves in north Florida. The prevalence of infections by Trichomonas gallinae was higher in white-winged doves (97%) than in mourning doves in south Florida (17%) or in mourning doves in north Florida (1%). The high prevalence of this parasite in expanding populations of white-winged doves may pose a threat to mourning dove populations since some strains of T. gallinae are pathogenic.
对佛罗里达州北部和南部本土哀鸽（泽纳ida macroura）的寄生虫与佛罗里达州南部引入的白翅鸽（z. asiatica）种群的寄生虫进行了比较。发现了32种寄生虫，包括5种原生动物、7种线虫、2种吸虫、2种绦虫、7种螨类、7种食毛目昆虫和2种双翅目昆虫。其中，16种是两种鸽子共有的。佛罗里达州北部的哀鸽显示出比佛罗里达州南部的白翅鸽或哀鸽种群更多样化的寄生虫动物群。线虫是所有三个种群中最常见的寄生虫；受感染的鸽子每只鸽子含有一到两种线虫。每只受感染的白翅鸽的总蠕虫负担平均为13.1，佛罗里达州南部的哀鸽为19.9，佛罗里达州北部的哀鸽为6.6。白翅鸽中鸡滴虫感染的患病率（97%）高于佛罗里达州南部的哀鸽（17%）或佛罗里达州北部的哀鸽（1%）。这种寄生虫在不断扩大的白翅鸽种群中的高患病率可能对哀鸽种群构成威胁，因为某些鸡滴虫菌株具有致病性。
