Affiliated to Dr. B. R. Ambedkar University, Andhra Pradesh, India ABSTRACT The` pelecanus philippensis and Mycteria leucocephala arrival and leaving secondary data were provide from 1992 to 2021 at Telineelapuram bird sanctuary. The Pelicans arrived from mid September to early October and left for end of April to May months. The Painted storks arrived from mid September to October ending and leave from May to June months. The Standard Deviation average values at 99.99% confidence level is the total number of both bird species 289.89 ±58.98 pairs was arrived and occupied 29.22 ±3.99 on different nesting trees for constructed nests. The total number of both bird species 382.33 ±39.06 pairs was arrived and occupied 40.33 ±8.67 on different nesting trees for constructed nests. The Pelicans were constructed nests average 181.67 ±34.33 and Painted storks constructed nests average 200.67 ±49.84 during 2001 to 2011. Pearson correlation coefficient is a measure of the strength of a linear association between two variables, where as the p-value tells us if the result of secondary data is statistically not significant. The results exhibit from 1992 to 2021 at every 10 years, the F probability null hypothesis for the full model is true for interpretation of the significance. KEYWORDS: Pelicans, Painted Storks, Standard Deviation, Pearson Correlation Coefficient, ANOVA, p-Value & F Ratio INTRODUCTION pelecanus philippensis (Spot-billed Pelican) and Mycteria leucocephala (Painted stork) colonies were close proximity and vicinity of the human settlements and close to roads. The breeding sites of the trees were belongs to the 3 acres of Bird sanctuary protected by A. P forest department and rest of the protected growing near to village houses. Painted storks feed in groups in shallow wetlands, crop fields and irrigation canals. The maximum success of finding prey was at 7 cm of water depth. They feed mainly on small fish and frogs which they sense by touch while slowly sweeping their half open bill from side to side while it held submerged. They walk slowly and also disturb the water with their feet to flush fish. During the mid day heat, adults will stand at the nest with wings outstretched to shade the chicks. To feed chicks, adults regurgitate fish that they have caught and these are typically smaller than 20 cm long. Densities are much higher in winter after chicks of the year have fledged from nests Painted storks breed on trees either in mixed colonies along with other water birds, or by themselves. The breeding season begins in the winter months shortly after the monsoons. About 25 sites in India are associated with wetlands support to Spot-Billed Pelicans and most of these sites are in south India, especially in the states of Andhra Pradesh, Tamil Nadu and Karnataka (Subrahmanya, 2005 and Original Article International Journal of Zoology and Research (IJZR) ISSN (P): 2278–8816; ISSN (E): 2278–8824 Vol. 11, Issue 1, Jun 2021, 29–38 © TJPRC Pvt.
