First off, the recommended size for a parakeet is 404x, and it is WAY TOO SMALL for my parakeet. I couldn’t clip it, but even when it was on her without being clipped, it was way too heavy for her head to hold up. Would not recommend for smaller birds.
It’s a great idea for a product but the material is so hard it gave my bird a raw spot so I had to take it off.
I have a 160g caique. Guidelines show 100-299g for size small and lists birds like starlings which are smaller than caiques. All listed as "small" examples.
Size small collar itself is slightly over 30g.
It is MASSIVE and super heavy. Need a really good pair of sharp scissors to make it usable and safe for smaller birds.
I would not recommend this product for birds under 200g.
Great product my birds love to pick it out of there water
