I threw some stale chocolate chip cookies into a cannel today and they were taken by by some Moorhens. Do you think the Theobromine in the chips will do them much harm?

Hi there! It's great that you're thinking about the well-being of the Moorhens. Chocolate, as you may know, contains theobromine, which can be toxic to many animals. Fortunately, in birds like Moorhens, the risk of theobromine poisoning is generally lower compared to mammals such as dogs and cats. Still, it’s wise to be cautious.

The amount of theobromine in milk chocolate is relatively low, but it's hard to determine the impact without knowing exactly how much chocolate was in those cookies. If the Moorhens have eaten only a small amount, they might not experience any ill effects. However, if they consumed a significant quantity, it could potentially cause issues like diarrhea or an upset stomach.

For now, you can monitor the area where you saw the Moorhens. If they seem lethargic or you notice changes in their behavior, it might be a sign that they aren’t feeling well. Unfortunately, direct at-home care for wild birds is challenging, so if you do observe any worrying signs, contacting a local wildlife rehabilitator would be a good next step.
