    MIT scientist, Stephanie Seneff, believes the epidemic of bird beak deformities is caused by glyphosate in Roundup-treated bird seed, causing the keratin to break down. Roundup is also sprayed on cane and beet sugars, so it would be in hummingbird nectar in feeders. For more info, contact Dr. Seneff: seneff@csail.mit.edu I heard her remarks on this in a video of a presentation she gave on glyphosate.

      Hi Kathy, We’ve not heard of any studies linking glyphosate to beak deformities, however biologists in Alaska have been studying bill deformities, also known as Avian Keratin Disorder, for some time. In 2016 a team of researchers from the California Academy of Sciences, University of California San Francisco, and the USGS identified a novel virus that has been linked to Avian Keratin Disorder. You can learn more about their research here.

    Thank you for the information! I have reported this observation to the USGS Alaska Science Center Beak Deformity and Banded Bird Observation Report.

    Just noticed an Anna’s with what may be a deformed tongue at one of my feeder’s near Woodinville, WA. Could this just be something stuck on her bill? I haven’t seen her feed, just sits on the feeder. I can send a picture.

    Another lady on a birdwatching site, has posted a picture of a hummingbird, coming to her feeder, with its toungue hanging out of its beak, to one side. It appears to be healthy otherwise. Can it actually drink from the feeder, or have been hatched with 2 toungues, or surviving some other way ?

    • Hello Nancy, after the photos were taken, I didn’t have any further contact with him and assumed that he might have passed away.

    We have well over 20 Anna hummingbirds at our feeders now, December, and one has shown up with a beak tip deformity. What is unusual about this particular bird is that it will not sit on the perch while drinking. The other birds seem to wonder what the fluttering is all about from this hummer but they still share the feeder quite well together. I will try to see if there is also bone deformity in legs or feet causing it not to perch. Our location is in vineyard country so I am interested in avian poisoning from local chemical spraying.

    Here in California we have had an annas male with a beak deformity at our feeder for almost year. It is very similar to this picture. He is a big larger, rounder, and slower than the rest. Nonetheless he viciously protects his preferred feeder. One of the flower and grate were missing from one side of the feeder when he showed up and her preferred that side. I can get very close to him and clearly see his beak.

    Hi there, We have a hum looks young with a mowhawk of sorts of odd feathers on very top of head. Some look micro long & thin & some protrude like ears. I have been feeding & birder for 20yr & have not seen this before. I have had a Allen male & wondering if this is a Allen juvenile. I would love to share any info or photo if anyone’s hears or seen this.

  8. I have a hummingbird with a sideways beek like a big hook on the end. It might be broken. I created an account so I could upload a picture but I can’t see where I can do that. We are concerned about his well-being.

  9. I’m in NJ & we have a hummer with a deformed beak. This is the first deformity we’ve ever seen with the birds and we’ve been feeding them for over 20 years. They seem to be doing okay. We have 2 well maintained feeders – one with little plastic “flowers” and the other one has little “cages” in the center of the flower – this is the one our little guy feeds from mostly (which hangs right outside my kitchen window), Their feathers are ruffled. We think it’s from them trying to groom themselves and the crooked beak only ruffles them more. The beak looks like it splits in 2 at the end like a “Y”. I’ll take photos and send them. We’re not interfering with them. Just observing. I found your website when I searched for “Hummingbirds with deformities “. Thanks for any help or information.
