 published range m^s (e.g., Leopold [1977] and Peterson and Chalif [1973]), but were not observed or 

 reported. 



Among mammals, several taxa were not observed during censuses. Two primates were 

 reported by hunters, but not observed during censuses: howler monkey (Alouatta pigrd) and spider 

 monkey {Ateles geoffroyi). The rabbit iSylvilagus floridanus) and the ring-tailed cat (Bassariscus 

 sumichrasti) were not reported. The porcupine (Coendu mexicanus), short-tailed weasel (Mustela 

 frenata) and Baird's tapir (Tapirus bairdii) were reported (pers. obs.). Among birds, three taxa were 

 expected, but not observed during censuses; the great tinamou (Tinamus major) was not reported by 

 local residents, while the crested guan (Penelope purpurascens) and the black-throated (Yucatan) 

 bobwhite (Colinus nigrogularis) were reported, but not observed. 



Relative Abundance 



Since the number of individuals sighted during the censuses was relatively low, three levels of 

 analyses were conducted: species (four species compared), taxonomic group (five groups compared), 

 and game versus nongame birds and mammals (four categories compared). These comparisons allowed 

 conclusions based on the available data. 



Species . Significant differences were detected for plain chachalaca sighting frequencies 

 between Late Secondary Forest without Gardens, Late Secondary Forest with Gardens, and 

 Combined/Early Secondary Forest (mean sighting frequencies were 1.9 individuals/ 10,000 km, 

 0.6/10,000 km, and 5.2/10,000 km, respectively; x^ approximauon = 8.4900, d.f. = 2, P = 0.0143; 

 Table 4-1). No significant differences in sighting frequencies were detected between forest successional 

 stages for squirrels (P = 0.1596), coatis (P = 0.0877), or kinkajous (P = 0.0665). 



Groups . Significant differences were detected for bird sighting frequencies between Late 

 Secondary Forest without Gardens, Late Secondary Forest with Gardens, and Combined/Early 

 Secondary Forest (mean sighting frequencies were 5.2 individuals/ 10,000 km, 1.3/10,000 km, and 

 6.8/10,000 km, respectively; x' approximation = 7.2692, d.f. = 2, P = 0.0264; Table 4-1).
