The Mysterious Egg Caper

 

 

From the trail camera is a curious couple of photos of a turkey hen with an egg in her mouth.

What gives?

So I sent-off an email to a certified wildlife biologist at the University. 

Hiya Jamie...   From the trail camera is a puzzler.  Why would a turkey hen be moving an egg?  I cannot imagine she could get her beak around an intact egg.  But I'm happy to be wrong on that. Or is this some sort of predatory behavior?  Thanks, as always, for any insights.  Tom 

To which she replied.

Hi Tom,  You always have the most interesting trail camera photos!  From my understanding, hen turkeys do not relocate viable eggs.  I believe that this is a hen removing an egg from the nest that was depredated to avoid attracting additional predators to the remaining eggs.  Predators like ground squirrels and crows may puncture an egg and consume the insides.  While turkey hunting this year, I came across a turkey egg right in the middle of a trail (see attached), this was probably a similar scenario, or a predator carried it this far.  This looks like a crow, or another bird used its beak to pierce the shell.  Starting to see quite a few broods of turkey poults, hopefully you are, too.    Cheers,  Jamie

The plot thickens.  Jamie forwarded the email chain to a colleague for further discussion.

Hi Chris,  I hope you are doing well!  Below is an email I received from a landowner as well as my reply.  It got me thinking and I'm curious if you have any other plausible explanations for the hen turkey with an egg in her mouth.  Have you documented any turkey nest predation by turkeys?   During my master's research, I did have a turkey depredate a grassland bird nest and I know of at least one grouse nest depredated by a turkey... all opportunistically, I'm sure.   I'd appreciate any thoughts you may have.  Have a great week!   Jamie 

And the response from Chris.

Hi Jamie,   Good to hear from you. Things are going well here. I hope you’re enjoying your summer thus far!   Well…this isn’t something you come across every day! I haven’t knowingly encountered an instance where a turkey has eaten an egg, although I have suspected it. I’m aware of colleagues in other states that have attributed egg loss to turkeys on occasion, but none to my knowledge have photos of a bird carrying an egg. I did come across one wildlife photographer who was able to document a similar occurrence and included it in a blog post (https://www.robertgroosphotography.com/home/the-egg-bandit).     Turkeys are very opportunistic. And while eggs are not part of their normal diet, they are eaten on (relatively) rare occasion. I think it most likely occurs when a bird comes across an abandoned nest; or in the case of a hen, if she is bumped off a nest and the eggs are partially eaten by a predator, she may return and consume the remaining egg(s) since they are highly nutritious – which could be especially valuable if she decided to renest. However, I don’t believe that turkeys are actively hunting for eggs, whether it be that of other turkeys or other ground-nesting birds (which comes up way too often in discussions on ruffed grouse). Hope this is helpful.   Cheers,  Chris

So there you have it.  A possibly opportunistic turkey keeping-up with housekeeping around the nest.

Never a dull moment around here and an opportunity to learn something new.
