Collecting alligator eggs

Steve and I had the opportunity to join a friend (Scott) on an outing to collect alligator eggs. Scott helps out a gentleman who farms alligators and has been egg collecting for the last 12 years with him.

A helicopter is used as well as airboats. As Scott's boat is the largest, we got to play "mamma gator" and ferry eggs from the collecting sites to the landing zone primarily.

The morning starts out with the helicopter showing up and off we go

This is what we're looking for. A large mound of vegetation, sometimes guarded by a very territorial momma.

The little R22 only holds two people, so the pilot will drop one person on a nest with nothing but an aluminum pole and an "egg basket" leave and go pick up someone else to drop them on another nest.

Here in FL you are only allowed to harvest 1 out of every 2 nests you find

When a nest has been collected, the pilot will pick the harvester back up and drop them somewhere near the airboats to collect a new egg basket and off they'll go to find another nest.

And here are the eggs. If the eggs are, or at one time were, fertile they will have a birth ring around the entire egg. Eggs that do not develop embryos will not have a birth ring around them.

Not all nests are found by helicopter. Some are found by walking and by the folk in the airboats.

In addition to taking the full egg baskets from the harvesters and supplying them with a new basket, we were able to participate in the egg collecting as well with nests that we found near different landing zones.

After carefully uncovering the nest, you begin marking all the eggs with a sharpie to indicate which direction is UP so that when you place them in the egg basket, you are properly positioning the eggs so you don't kill the embryos.

The nest that I was on, there were about 30 eggs collected.

Steve also got in some action as well.

Hey check it out! There's a baby dinosaur growing in here!

At the nest, momma was absent, but that is not always the case. And sometimes momma is quite aggressive in regards to trespassers, though usually a good bonk or two on the head from the aluminum pole will help keep her at bay.

After taking big bunches of nests back to the landing zone, there was more work.

The eggs had to be removed from the egg baskets to be put into their permanent homes for the incubators....that is when all the counting of eggs got done, and then later candeling of the eggs to see which ones are "bad".

It is a very hot, dirty, sweaty, tiring job....but I guess someone has to supervise

It was a lot of fun though. i hope I can get to do it again in the future. Storms cut our day short, but we managed to collect about 700 good eggs. Another couple of dozen that were deemed bad.

Wow, quite an adventure Dani, but i'm glad we don't have em here in Nj mashes. 700 eggs, good lord, how many nests you guys found??

So if you can only collect one nest of every two you find, then the next person who comes along can only collect one of every two, how are there any left?

Maybe a stupid question and maybe there are only a limited number of egg collectors but enquiring minds are curious.....

I believe that collectors are assigned areas. And there are LOTS of nests, no shortage of alligators in FL!
 
That's pretty cool to be able to have the opportunity to be apart of. I am sure the are lots of jealous people reading this, I know I am.
 
Dani, Looks like fun except for mama cruising in. Did you really tap her on the nose?????? Say Hi to Scott for me, hope all is well for all of you.
 
I don't remember the number of nests off the top of my head, but it was around 25. The average clutch size is about 30 eggs, though we did have one nest that had 44 eggs.

You are not allowed to collect on state land, only private land. You have to have permission from the landowners and only that harvester is allowed on that property. FL allows for 30 egg collector permits only. Most of them are given to people who have had the permit for a long time, so I would imagine it's difficult to get a permit if you're new to the farming business, but I don't know that for sure.

Funny you say that Carl. We were talking with the head harvester and he was saying that in the area we were collecting in many years ago, it would take two and a half days to harvest the area. They'd get over 1000 eggs a day. They were struggling to find even the 700 that we found, and they were not planning on spending more than half a day the next day out there, and that's mostly because the storm ended the day early. He said that he started seeing a dramatic drop in the number of nests they were finding a couple of years ago. Perhaps some of them are on the state land that borders the ranch we were on. But it kind of reminded us of the sea turtles and how when you over collect the eggs, eventually it becomes more and more difficult to get breeding adults. So, you'll get fewer nests. Yes we have lots of alligators, and certainly they're in no danger of collapsing at this point. Perhaps though there is some localized correlation with the harvest and fewer nests. Though as likely it could be something along the lines of not ideal water depths or a bad year for the mommas.

I read that only about 15% of the hatchlings make it to 4ft long in the wild, and once the alligators reach that length, they have a very good chance of surviving to adulthood. In LA, 12% of the alligator eggs that are harvested and then the babies grown to 4 feet are returned to the wild. Here in FL the eggs are harvested and none are returned to the wild. Perhaps not a bad thing here in FL because we do have a lot of them, it is just an interesting thing to watch and learn about.

Tom-

I didn't have the opportunity to do any nose tapping or head bonking of perturbed momma gators....but I would've liked to have had.

Things are going great here. I shall pass along the hello to Scott.

Well, Dani, I sure do admire your tenacity and down right intestinal fortitude! Loved this thread.

Yes we have lots of alligators, but clearly they're not harvesting as many eggs as they used to in the past.

In LA, 12% of the alligator eggs that are harvested and then the babies grown to 4 feet are returned to the wild. Here in FL the eggs are harvested and none are returned to the wild. So, if you're taking half of the eggs out of the equation for wild alligators in FL, then you ought to expect the population to drop over time. Perhaps not a bad thing here in FL because we do have a lot of them, it is just an interesting thing to watch and learn about.

Thanks. Was curious how that worked. Looks like fun. Best we can do up here is collect Walleye eggs - hardly a dangerous affair.

No problemo Mark. And here's something else interesting. The harvester has to pay the landowner $8-$10 PER EGG plus the state of FL $2 PER EGG just to transport on the roads. We figured it out that between paying workers, the helicopter, the biologist that is required to go with you, the state and the landowner it was coming out to cost the harvester about $30 PER EGG. And that is before you even get it to the incubator. Pretty mind boggling really.

Why not candle in the field like they do with duck eggs? Are the shells too dense to get enough natural light through?
 
Ray-

Part of the reason they collect all of the eggs for candling later is because candling all the eggs when you have a pissed off momma gator at the nest would be difficult if not dangerous. I would guess that if ducks bit and ripped your hands off there'd be a lot less candeling in the field. Also, since unfertile eggs won't do anything in the nest anyway, you lose nothing when you take them. We do candle in the "field"...but it's back where all the trucks are parked and where there is shade and food and ice cold water, tea and gatorade. The nonfertile eggs get fed to the bass and bluegills in the canal and are not paid for. The harvesters only have to pay for the eggs they take off the property, which in this case are the fertile ones.
