As the safari guide cruises across the African savannah, with wild cheetahs stalking gazelles and thousands of wildebeest amassing in huge herds, no one is looking for a finch-like bird. But after a few days one starts to wonder: what are all those grassy clumps in the trees?
Those are weaver nests.
Weavers are a large family of colorful songbirds similar to finches, and they are one of the most architecturally-talented birds on the planet.
There are 64 species in the Ploceidae family, found primarily in sub-Saharan Africa. They do not migrate, living year-round in warm climates.
To learn more about the bird, visit Wikipedia Weaver Bird. You will see there are more than just 64 species from the Ploceidae family; additional weaver birds in other taxonomic families total 117 species.
The nest is built with grass found in the immediate vicinity. The males build the nests; females choose their mate based on the nest’s location, design, and comfort.
Typically bird nests are either open cups or hidden inside tree cavities. But not the weavers’. It is cylindrically shaped; with a narrow entrance hole usually facing downward to deter predators. In the African savannah, where predators abound and trees do not, the weavers have cleverly designed an enclosed grass clump hanging from a tree.
Named for their weaving abilities, the male uses only his feet and bill to weave the elaborate construction. First he tears grass blades and other materials into long strips, then he loops the initial strands onto the tree limb.
Next he intricately weaves the grass to form the hollow body; last, he creates the tubular entrance.
The weaver birds reside in many different countries, each with different habitats, so the building materials vary. Notice in the photos above, the dry grass around the Zambian village is reflected in the weaver nest built nearby.
Moreover, each weaver nest design is species-specific. I have included diagrams from my field guide (Birds of Kenya, by Zimmerman, Turner, Pearson, 1999) to demonstrate how consistent this is.
Number 1 in the first diagram, for example, belongs to the African Golden Weaver. Numbers 10a and 10b in the same diagram, each with dual parts, is home to the Spectacled Weaver. The tree in the second diagram, labeled 10a, shows multiple Red-billed Buffalo-Weaver nests.
The Sociable Weaver has the most elaborate nest of all. They are colonial nesters and build massive nests that can weigh up to a ton. One nest can have over a hundred pairs of nesting sociable weavers, and additionally host other non-weaver species concurrently. This nest is the largest built by any bird on earth.
Regardless of how many birds are occupying the nest, sometimes a pair only, there is a lot of color and chatter and acrobatics.
When we watch television documentaries about the African savannah, it looks like there’s an adrenaline-raising chase going on all the time. In reality, there are certainly moments like that, but often lions are sleeping during the day after a night of hunting; or there’s no action in sight. There are definitely lulls.
This is a good time to seek out the weavers. Because they never seem to stop and rest, they are busy with their home-building tasks always. And it’s no wonder–there’s a lot of weaving to be done.

Wow, some of those nests are spectacular Jet, thanks for sharing them.
They are indeed spectacular nests, Andrea. And the more one travels around Africa, the more you see the different structures and marvel. Thank you, as always, for your wonderful visit today.
Another awesome jaw dropping post Jet 🙂 As a tapestry weaver I am seriously impressed with what these birds can do. Do you think the Spectacled Weavers build more intricate nests because they can see better? Please don’t harangue me too much for my awful sense of humour lol 😉
I can’t believe the size and weight of those multiple nests or should I say condominiums.
Enjoyed the weaver humor, Alastair, you got me laughing. Tapestry weaving is an interesting hobby, Alastair, I am glad to share the many grass tapestries with you. Always fun to have you stop by, thanks very much.
Tapestry weaving is a lot more than a hobby for me Jet – it’s what I originally trained in! See http://www.alastair-duncan.com
Oh how wonderful, Alastair. Your website was eye-opening, and your tapestries are gorgeous. I found the colorful geometric ones especially attractive, and I smiled when I saw the community project because it looks like the Wales countryside photos I love so much on your blog site. I so admire tapestry, thanks for sharing your expertise, my friend.
Thanks very much Jet. I exhibited in California about 15 years ago when California Fibers and New Fibre Art (UK) exchanged exhibits. I was one of the organisers at this end. I’d love to visit someday. In the meantime my current project combines StillWalks and tapestry in a Sound and Weave exhibition for the British Tapestry Group!
How very wonderful to combine your expertise in sound and tapestry. If you are ever in the Bay Area, Alastair, let me know. I have some amazing frog and cricket sounds where I live. Weave on!
I’ve been interested in weavers when one year long ago I saw a nest woven by some house sparrows in Central Park. I wonder still how that happened. Perhaps they reverted to some ancient genetic link to African Weaver Finches? Love you post Jet.
Love this comment, Sherry. Perhaps they did revert to their genetic link, it’s fascinating to think about. Glad you enjoyed the weaver post…my thanks.
🙄
Sociable Weaver nests, Wow!! How did they do it. So carefully constructed.
Thank you for introduce it to us, Jet!
Happy you enjoyed the weaver nest post, today, Amy. They are an incredible family, it’s great fun to introduce you. Many thanks–
Will search on Youtube through our Smart TV to watch it. 🙂
Jet you have taught me so much about birds since I began following you but honestly this may be the most astounding thing yet. I thought it amazing just to think of males madly weaving up home sweet home to outdo the neighbours. However that sociable condo unit idea on steroids is mind boggling. Weighing up to a ton?! Some poor snoozy lion is going to get a heck of a concussion should an afternoon nap coincide with a faulty building plan.
Now I’m concerned these may have been present in the trees during our time in Africa and we didn’t even know it! Too busy watching herds of elephants and necking giraffes to see the architectural wonder going on in the trees.
Astounding Jet. Loved this post.
Your comment was a joy, Sue — your realizations and humor had me laughing. The weavers do not get top billing on African safaris, which is understandable; so I’m glad I could share their mastery with you here today. It’s less distracting here, when you’re not bumping along on a savannah jeep. Much appreciated, Sue.
Thanks, Jet. Weavers are incredibly fascinating and would make a wonderful study for anyone remotely interested in bird life whether the lion sleeps or not!
I agree, Walt. Fortunately there have been many studies. I used those field guide diagrams so much that I wrote inside the front cover what page number they were on, for quick reference. Thanks so much for your visit and comment.
Many thanks Jet.
xxx Massive Hugs xxx
And my many thanks to you, too, David. Thanks for the hugs, and more back to you. ooxxoo
Thanks, Jet. I’m always learning here. These birds are amazing, building and weaving from grasses and such. When you really stop and think about what they’re doing, it is astonishing! I’m still happy when my bootlaces get tied…
Thanks again, and have a wonderful weekend!
It truly is astonishing when you think about it. It’s a stark world they live in, but they’ve managed to keep proliferating, largely due to the ingenuity of their building techniques. Always a treat to teach a teacher something, many thanks for your delightful visit today, pc. I’m heading north for the weekend, should be fun — I hope it is a fun one for you, too.
Holy cow, Jet, those are some serious nests!! But I guess apartment/multi-family homes are always larger. 🙂 When I spot something here similar to that first shot, it tends to be a hornets’ nest, so this was much nicer.
janet
It’s really fun to see them all. Often there are quite a few closer into the human establishments, too, where there are more trees. I’m glad you enjoyed the weaver nests, Janet. Good point about the hornets’ nests — you wouldn’t believe how huge they get in Africa. Thanks very much.
Really interesting, Jet. Aren’t they colourful birds? Wow, their nests are so impressive! Enjoyable read, thank you. 🙂
I am happy you enjoyed reading and viewing the weavers today, Iris. Always fun to have you drop by….
a beautiful find
and wonderful
lesson, Jet 🙂
I have a reverence for weavers, I guess because it is something like weaving a novel. I’m glad to have shared the weavers with you today, David, thank you very much.
Wow, those nests are incredible, Mother Nature truly is amazing!
And there is no end to what Mother Nature shares with us. A very fortunate thing for us earth-dwellers. Thank you, Joanne. Enjoyed your Mother Nature post today, too.
Wow! the nests are a work of art and the sociable weaver nest is incredible. it is huge and can weigh up to a ton is simply mind-boggling. the nest on an electric pole is a structure! i wonder how long it takes to build? Jet, thank you very much for all your awesome posts! i am learning a lot. wishing you a great weekend! 🙂
The electrical poles are becoming more of a tool for the sociable weavers, isn’t that a crazy photo, Lola? Indeed they are a mind-boggling species, happy to share them with you, Lola. Thanks so much.
I very much enjoyed learning about the weavers from your post. It’s so fascinating to know how such elaborate nests were built by these birds. The picture of the bird weaving green grasses into a nest answered a naive question I had about how in the world these birds could weave dry leaves into a nest. Duh.
I liked that photo, Keng, for exactly that purpose–to demonstrate how a bird could weave. I am delighted you were engaged and interested, and appreciate your visit and comment.
Makes me think birds will be the next dominant species! Amazing.
Ha. Yes the weavers really have it going on, don’t they, Jan? Thanks very much.
What a pleasure to see weavers again! Where did you go in Zambia?
We were in Lusaka and travelled by jeep throughout the Luangwa Valley and also on the Zambezi River. Thanks Cathy, I am so glad you have seen weavers.
Wow, Jet, you sure get around! 🙂
Yes, I do get around. I set my goals and charge ahead. Thanks for traveling to Zambia with me today, Tom.
Fascinating post and I had no idea that there was a bird that created these amazing nests, especially the sociable weaver nest. I enjoyed your comment about the lull in activity on the safari, I often will change the channel when documentaries concentrate solely on the animals stalking their prey. Loved the shot of the Zambia Village and learning about these interesting birds.
Thanks so much for your thoughtful comment, ACI. It is interesting to see the grass nests around villages, and the little kids always wave as we cruise by. The teenagers never wave, and the adults usually do not look up. But the little ones, they shout the word “candy” in Swahili and wave and smile. We never stopped, as it wasn’t good to hand out candy (no dentists). And I, too, don’t particularly like the documentaries that are solely about the chase; they’re misleading about true life on the Serengeti. Always a pleasure, ACI.
The Taveta Weaver is the only bird of this kind I van on my list. I was so impressed by their intricate woven nests. You have defined a good bunch of weavers most likely related to one another. Great post my friend. 🙂
When I was preparing this post I looked on my bird list (I am an avid lister) and was surprised to see I have seen 29 weaver species. There are so many species. I am not familiar with the Taveta, so I liked knowing you saw it, HJ. Many thanks for your visit, HJ, I hope this week was a successful healing event for you.
I’m taking Biology this semester. I’m fascinated with the way animals adapt and the skills they possess to do so. Cant help but be jealous. 😀
Animals can teach us humans a lot about adaptability, right, Rommel? Enjoyed your insight, thank you so much.
We only seen 3 weaver species and their nests, too – all in Tanzania. Thanks for all the information about their amazing nests and how very different they can be. Amazing birds!
How wonderful for you to have been in Tanzania, it is one of my favorite places on earth. I am glad you have seen weavers. Thank you for your visit.
I had no idea about those huge colonial nests. Another cool aspect of the earth.
I am happy to have introduced you to the weavers, Dave. Thank you for stopping by.
“There is a lot of weaving to be done..” especially if you are a Sociable Weaver! Wow! Thanks for this post Jet.
Hi Bertie — great to “see” you. I’m happy you enjoyed the weavers, thank you.
When’s the ♥️ Button…. those sociable weavers create something beyond imagination! Thanks for opening my eyes and mind Jet.
A great joy to share the amazing weavers with you, Val. Thanks for the warm comment and visit.
Enjoyable and informative post Jet!
Thanks very much, Belinda — I’m happy you enjoyed the weavers.
I’ve learned so much about nests from your post, Jet! Such a great read and so many stunning pictures!
I’m glad you enjoyed it, Agness, thanks for stopping by.
I never get enough of the bits you teach me! This was fascinating! That giant nest is pretty mind-boggling.
Always fun to hear from you, Gunta, and sharing the weavers was a joy. Thanks so much for your visit and comment.
I have seen weaver nests many a place and they are fascinating constructions. I enjoy reading your account about them, and especially enjoyed your photos. A beautiful post.
The weaver nests are memorable, and yes, fascinating — how wonderful you have seen them, Otto. Thank you for your visit and kind comment.
Amazing! I found some wonderful videos on YouTube of them building their nests. Thanks for sharing another fascinating post.
I’m glad the weavers ignited interest for you, Nan — and as always, such a delight to have you visit. Thank you so very much.
This was absolutely amazing! Nature is so incredibly magical!
I particularly appreciated this:
The males build the nests; females choose their mate based on the nest’s location, design, and comfort.:)
Thanks very much for your perceptive comment, Carol. I worked on that sentence…sort of like the foundational twig in my own nest. Warm wishes to you–
I am intrigued by the weaving skill of the male…so the very intelligent female checks out whoever builds the best home in the best place…..natures way!! 🙂
Yes, the weavers are fascinating, aren’t they? Their nests, their weaving, the many species, and behavior. Glad I could share them with you here. Thanks so much, Kirt.
What extraordinary birds. I’d love to see them in real life… one day, maybe! RH
You have a very good chance of seeing the weaver birds, RH, fortunately they are a very successful breed. Many thanks for your visit, always a pleasure.
Amazing nests!
Thank you, Kendall — and the variety of the different nests is amazing too. Quite a bird. Cheers to you.
Welcome and cheers to you, too!
I love this, especially the one ton nests. How totally amazing! Thank you, Jet!!!
Imagine a one-ton nest! And since electricity has been introduced, the poles are a helpful tool for the weavers (but not so good for preventing electrical fires). Thanks for your visits today, Resa, much appreciated.
It is impressive how they build their nests! The sociable weaver is especially remarkable!
What a bird species the weaver is, I’m happy you enjoyed it, Indah.
What a special bird! Those colonial nests are amazing.
Thank you, Inese — great to “see” you, and I’m glad you enjoyed the weavers.
Haven’t been around since April, Jet. Nice to be back.
Nice to have you back, Inese. 🙂
Your post are always educational, thank you 🙂
Those weaver birds are an interesting lot, aren’t they, John? I’m glad you enjoyed them. Thank you for your visits and comments.
