|Canada Gosling amongst daisys at York University|
Today I thought Id'do a few facts on each type of gosling I saw, I've linked to my posts where I've covered these birds before. So, here are the facts:
- Their eggs weigh quite a lot but it's actually only 3.5% of there usual 4.6kg weight. If you're extremely good at maths then you'll know that their egg weight is only 163g!
|Canada Goose and gosling|
- The standard Canada Gosling usually only has between 4 and 6 siblings in each brood, there is only one brood a year.
- Eggs hatch in 28-30 days and chicks fledge 40-48 days later
- Goslings only breed once they reach 3 years which is half of their life as they live for an average of 6 years.
- There eggs weighs a quite remarkable 5% of the average Greylag adult weight at 160g. (The average Greylag Goose weighs 3,300g.)
- Just like the Canada Geese there are 5-7 eggs in a brood.
- They hatch in a similar time, after 27-28 days but take a little longer to fledge 50-60 days later
- Again like the Canada Goose they breed when they reach 3 years old but they have a slightly longer average lifespan at 8 years old.
|Barnacle Goose and goslings|
- Barnacle geese are smaller than the first two at just 1.7kg. Their eggs weigh less too but at 107g they are over 10% of their body weight each!
- I don't know if that is why but their average clutch size is smaller at 4-5 eggs.
- They hatch a little quicker, after 24-25 days and fledge after 40-45 days later
- These geese also breed when they reach 3 years old but they have a much longer average lifespan at 14 years old.
- Snow geese are smaller than the first two species but larger than Barnacles at 2.3kg but I couldn't find their egg-weight.
- In fact as they are mainly a North American bird I wasn't able to find out much about their lifespan or hatching time etc. either!
- I will have to do more research and come back to a post about these birds.
- So I hope you'll be happy with just a picture of a cute gosling.
If I get time to edit another video watch out for Cuteness Overload Part 2 tomorrow. Off for a great wild adventure though so it may have to be on Sunday.
Hope you enjoyed.
