With the objective of identifying the types of present parasites and their environmental preferences in 5 psittacines species (Ara militaris, Amazona aestiva, Amazona autumnalis, Amazona Finschi and Aratinga canicularis), it was carried out a traverse investigation, to study the effect of the humidity and the environmental temperature on the presence of gastrointestinal parasites, they were carried out fecal tests once a month, during 12 months analyzing 60 excrement samples using the Technique of Willis and direct observation with Lugol with increase of 40X, took data of humidity and environmental temperature every month to the captive wild birds in Ara militaris, the observed parasitic gender was of mature Nematodes with 91% of presence, Ascaridia spp 66%, Cestodes adults 50%, Tetramers spp 41% and Eimeria spp 25%, in Amazona finschi, the observed presence were cestodes mature 91%, nematodes mature 75%, Raillientina spp 41%, Hymenolepis spp and Eimeria spp 33%. For Amazona autumnalis to 21°C, it was more abundant in all the parasitic goods and in Amazon aestiva the presence of mature Nematodes was of 33% in temperatures from 13°C to 18.8°C and superior temperatures (19°C at 27°C), one observes in 0.83%, in Aratinga canicularis there was no significant difference, since of the 13°C at the 20°C 29 parasites were observed and of the 21°C at the 27°C 30 were observed.

The wild birds are host of great variety of parasites however few works exist about the species of parasites that attack these animals in captivity, (Acuña and Hinojosa, 2005). Among the numerous problems of health that affect the wild birds, the parasitic illnesses stand out like one of the most frequent as it gave Fabbio, (1996). Lim., et al. (2008), it points out that the occurrence of parasites can vary according to the handling type and administered treatments, regarding this, Epstein (2002), he mentions that the birds among other alive beings are indicative biological of the environmental contamination and of the illnesses that are in a certain place. For the study of anything species in particular and their later conservation is fundamental to have the knowledge of the natural atmosphere that surrounds it, (Parada 2000). According to Troncoso., et al. (2013) there are few studies on the microorganisms of the gastrointestinal tract of the psittácines neotropicales, but it is possible that some of the microorganisms that compose it can be zoonótic. The wild birds are hosts of a great variety of parasites, but few studies carried out in zoological exist and centers of rehabilitation of wild fauna, (Octavio., et al. 2013), many birds maintained in open aviary are easily infected by grounds of free wild birds which can contain a great number of parasites, (Cole, 2007), According to Martínez (2006), the captive and small populations are, particularly, susceptible to stochastic processes, including buds of illnesses that can end up causing them the death. Frequently Trichomonas spp is., in the grounds of asymptomatic psittcines, (Samour, 2008), according to Müller, Greinert and Silva, (2005), most of the intestinal parasitic infections are asymptomatic, the young animals infected can be however gravely and to manifest illness signs. Blood and Rodostits (1992) they point out that the climate is an important factor so that they happen the infections for parasites. According to Beltrán, Angulo and González, (2009), the effect of the climate on the parasitic epidemiology is governed, mainly, for the humidity, that is to say, it is related with the patterns of the pluvial precipitation, to that which Gállego (2007), he mentions that, the environment plays a very important paper in to allow or to impede the development of the parasites in certain geographical areas. In Mexico few studies exist in populations of wild birds in captivity, for such a reason, presently work you estimate the parasitic frequency in 5 species of wild birds under captivity conditions in the state of Jalisco, Mexico.

They were carried out samplings fecal tests once a month, during 12 months, to a group of wild birds under captivity conditions, the population consisted of, Amazon finschi (n=3), Amazon aestiva (n=1), Amazon autumnalis (n=4), Aratinga canicularis (n=1) and Ara militaris (n=8), it was analyzed a total of 60 excrement samples using the Technique of Willis and direct observation with Lugol with increase of 40X, they took the environmental data as humidity and environmental temperature during every month.

Experimental design
Was carried out a traverse investigation, to study the effect of the stations on the presence of gastrointestinal parasites in the captive wild birds, that is to say that is related the problem with characteristic climatologically specific in certain moments. For it, it was considered in a combined way every month of the year of study, according to Pineda, Alvarado and Canales, (1994), a traverse investigation is carried out when "the variables are studied, simultaneously, in certain moment, making a cut in the time". It was also carried out a study correlacional, because this it tries to verify the possible relationship between the climatic factors and the presence of parasites in the different months of the year of study. For Tamayo and Tamayo (1999) "In this investigation, it is pursued, fundamentally, to determine the grade in the one which the variations in one or several factors are concomitant with the variation in other or other factors". The variables of this investigation were the following ones: 1) factors of the environment; temperature and environmental humidity, which were measured every month during 12 months, (as independent variable) and, 2) the presence of the gastrointestinal parasites, (as the dependent variable). All the materials and methods that are used to complete the study should be mentioned.

In the figure 1 are observed that the most frequent parasitic gender found in the 12 months of sampling, was the mature Nematodes with 91% of presence, continued by eggs of Ascaridia spp with 66%, adults Cestodes in 50%, eggs of Tetramers spp in 41% and Eimeria spp in 25%.

The previous table is observed that of the 12 samplings carried out during the year, in the case of Amazon finschi, the parasitic gender with more observed presence, they were the mature cestodes with 11 observations of the 12 samples, giving 91%, followed by the mature nematodes with 75% of presence, Raillientina spp with 41%, Hymenolepis spp and Eimeria spp with 33%. 

The previous figure is observed that during the months of November and December with temperatures of 18.8°C and 15.5°C the parasitic presence went respectively, smaller to the months of February and March with temperatures of 13°C and 22°C respectively.

As it is observed in the previous table the presence of mature Nematodes it was more observed in 33% in temperatures from 13°C to 18.8°C, while to superior temperatures (19°C at 27°C), alone one observes in 0.83%.

As we can observe in the table 3, there was no significant difference since in the difference of temperature from the 13°C to the 20°C (that was the average of temperature) 29 parasites were observed and of the 21°C at the 27°C were observed 30 parasitic goods.

• For Ara militaris the most opposing parasitic gender was of mature Nematodes with 91% of presence, continued by eggs of Ascaridia spp with 66%, Cestodes adults in 50%, eggs of Tetramers spp in 41% and Eimeria spp in 25%.
• In Amazona autumnalis, during the months of November and December with temperatures of 18.8°C and 15.5°C the parasitic presence went smaller to the months of February and March with temperatures of 13°C and 22°C this coincides respectively, with that carried out by Gurler et al., (2010), where he found a decrease during the autumn of parasitic infections in birds of a zoological one of Turkey.
• In the case of Amazona finschi, the parasitic gender with more observed presence, they were the mature cestodes with 11 observations of the 12 samples, giving 91%, followed by the mature nematodes with 75% of presence, Raillientina spp with 41%, Hymenolepis spp and Eimeria spp with 33%.
• In the case of Amazona aestiva the presence of mature Nematodes was more observed in 33% in temperatures from 13°C to 18.8°C, while to superior temperatures (19°C at 27°C), alone one observes in 0.83%, what agrees with the works carried out by Opara et al., (2010) and Raja et al., (2014).
• In Aratinga canicularis there was no significant difference since in the difference of temperature from the 13°C to the 20°C (that was the average of temperature) 29 parasites were observed and of the 21°C at the 27°C were observed 30 parasitic goods.
• When carrying out a seasonal identification of the parasites of the captive wild birds, it allowed us to know the epidemic status of the birds and with it, to develop preventive, therapeutic measures and of adapted control, diminishing with this the negative effects that have the parasites on the birds and improving their quality of life, besides diminishing the risk of transmitting pathogens to the human beings in contact with these animals.
