What happens with alka seltzer in a pelicans mouth?

When a pelican consumes Alka-Seltzer, the effervescent tablets react with the moisture in its mouth, releasing carbon dioxide gas. This rapid gas production can cause the pelican's stomach to expand, potentially leading to discomfort or even rupture if the volume is excessive. Additionally, the ingredients in Alka-Seltzer, including sodium bicarbonate, can disrupt the bird's digestive system. Overall, it's harmful and not suitable for pelicans or other wildlife.
