Online published on 28 March, 2024. Abstract The study on extent of damage by avian fauna in maize and measures for management was conducted at ICAR-Krishi Vigyan Kendra, Virudhunagar District, Tamil Nadu. The per cent cob damage was assessed at the time of harvest. In addition, the bird species and its nature of damage also recorded. The results showed that, three rows of pearl millet in the border area combined with placement of reflective ribbons and scare crows (12/ha) had recorded least cob damage (32.29%) followed by treatment with placement of reflective ribbons and scare crows (12/ha) (35.43%) as against 68.29 per cent in the control plots. The yield also comparatively higher in treatment imposed plots (6242 and 5400 kg/ha), while the control plots registered 4562 kg/ha. Mostly the bird species viz., Columbia livia, Psittacula krameri and Corvus splendens were primarily causing damage to the maize crop.
