# Animals That Start With B

> This is WARN’s list of animals that start with B — 47 sourced wildlife guides from the babirusa to the butterfly. 12 of those guides sit in an IUCN threatened category (Critically Endangered, Endangered or Vulnerable). The list is WARN’s published library, not a census of every B-animal on Earth. WARN funds partners in 17 countries; overlap with a range is geography, not a letter grant.

## In brief

Browse 47 animals that start with B in WARN’s free wildlife-guide library. Babirusa, Baboon, Badger, Bald Eagle and 43 more each open a sourced guide. This is not a catalogue of every species whose English name begins with B.

## At a glance

- 47: B guides
- 12: IUCN threatened on this letter
- 491: Guides in the full A to Z
- 26: Letters with WARN guides

Threatened counts follow each guide’s IUCN category (Critically Endangered, Endangered or Vulnerable). Group guides may use a status label when one badge would mislead. This is not a census of all animals.

## This is not the right page if you want

- A complete list of every animal on Earth that starts with B. WARN currently publishes 47 guides for this letter, not a zoological census.
- To look an animal up by any letter. That encyclopaedia is /animals-a-z/.
- To adopt a dog or cat into your home. WARN does not rehome pets — that is /directory/.
- A named animal with photo updates. Symbolic adoption is /adopt/; monthly sponsorship is /sponsor/.
- To donate without browsing this letter. That is /donate/ or /appeals/.
- Gift Aid or a UK charity receipt from WARN — that is /about/registration-status/.

## How to use the animals that start with B list

Stay on this page to scan WARN’s 47 wildlife guides whose common name starts with B. Confirm you want a sourced species guide, not a local pet. Then open a name, read the IUCN context, and give at /donate/ if you also want to fund partner-led rescue.

1. **Confirm you want this letter** — Stay here if you searched “animals that start with B” or need Babirusa, Baboon, Badger, Bald Eagle and 43 more. If you wanted every letter, open /animals-a-z/. If you wanted a rescue shelter for dogs near you, stop and open /directory/.
2. **Scan the named guides** — The table lists each common name, scientific name and IUCN label from the guide. Counts are WARN guides, not species in nature.
3. **Open the sourced wildlife guide** — Each name opens a wildlife guide with facts, IUCN context, habitat, threats and FAQs. Group guides say when one Red List badge would mislead.
4. **Give if you want to fund rescue** — This letter page is an encyclopaedia, not a checkout. Use /donate/ or pick an appeal that matches the animal you just read about. You do not get a named animal. Gift Aid is not available.

## What animals start with B?

Animals that start with B, in WARN’s library, are Babirusa, Baboon, Badger, Bald Eagle and 43 more. There are 47 sourced wildlife guides on this URL. The heading matches the search; the inventory matches the guides.

B is one of the busiest letters in this library (47 guides). That is because English common names cluster, not because WARN ran a special B project. Use the table to jump rather than scrolling a dumped worksheet.
Sorting uses the common name. Scientific names still appear in the table. Babirusa is first on this letter because of English spelling, not because it is more important than Butterfly.

## How many animals start with B?

WARN currently publishes 47 wildlife guides whose common name starts with B. 1 is listed as Critically Endangered. 12 sit in an IUCN threatened category.

Those numbers count WARN guides, not life on Earth. A group guide still occupies one slot. When WARN publishes another B-animal, the count on this page will move.
The A to Z hub at /animals-a-z/ holds 491 guides across the alphabet. This letter is 47 of that library.

## Is this every animal that starts with B?

No. This page indexes 47 WARN guides, not every species whose English name begins with B. Missing from the list means the guide is not published yet — not that the animal does not exist.

Search engines still send “list of animals that start with B” to pages like this. The honest answer is the count on the page. IUCN has assessed tens of thousands of animal species; this site publishes a curated, sourced subset.
For the full WARN index, use /animals-a-z/. For extinct animals WARN has covered, use /wildlife-guides/extinct-animals/.

## Does WARN rescue animals that start with B?

Not as a letter. Many of these guides are educational. WARN funds rescue and conservation partners across 17 countries. Each B-guide notes where WARN is, and is not, currently active.

A heading that implied every listed animal has a WARN field team would be a lie. Reading a guide is free either way. If you want to fund partner-led work, that is /donate/ or /appeals/.
You do not get a named babirusa from a gift. Entry-tier gifts pool across the programme.

## How are animals that start with B sourced?

Each guide’s facts are checked against the sources on that page — IUCN Red List and CITES where status and trade listings apply. This letter page does not invent counts the guides do not support.

Do not treat a letter heading as an IUCN assessment. The assessment lives on the species page. Editorial standards, corrections and AI disclosure live at /about/editorial-standards/.
Markdown twins of this letter sit at /llm/animals-that-start-with-b.md for answer engines.

Yes. Each wildlife guide cites IUCN Red List and CITES where those datasets apply, plus the references on that page. This letter index does not add unsourced extra B-animals to look complete.

### What is the difference between this page and a species guide?
