Wayne J. Arendt Jan Kalina Grey W. Pendleton Gerald D. Lindsey 1991 <p>We studied home range and movements of 15 radio-marked, juvenile Puerto Rican parrots (<i>Amazona vittata</i>) fledging from wild nests during summer and fall, 1985-87. When juvenile parrots remained in the nest valley, home ranges during 1986 (<i><span>x̄</span></i> = 32 <span class="l_ecrd_txt_pln">± </span>10 [SE] ha, <i>n</i> = 4) were larger (<i>P</i> = 0.0079) than during 1987 (<span><i>x̄</i></span> = 13 <span class="l_ecrd_txt_pln">± </span>6 ha, n = 5). After radio-marked parrots integrated into adult flocks, home ranges during 1986 (<i><span>x̄ </span></i>= 1,075 <span class="l_ecrd_txt_pln">± </span>135 ha, n = 3) were similar (<i>P</i> = 0.10) to 1987 (<i><span>x̄</span></i> = 416 <span class="l_ecrd_txt_pln">± </span>62 ha, n = 2). Juvenile parrots restricted their movements to nest valleys an average of 58 <span class="l_ecrd_txt_pln">± </span>29 days following fledging. After joining adult flocks, juvenile parrots routinely flew between the east and west slopes of the Luquillo Mountains but did not exhibit a seasonal pattern of movement. We recommend that captive-raised, juvenile parrots used in release programs be <span>≥</span>5 months old to ensure they are mature enough to integrate into wild flocks.</p> application/pdf 10.2307/3809157 en Wiley Home range and movements of juvenile Puerto Rican parrots article
