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.

Who should skip this

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 to Z.
  • To adopt a dog or cat into your home. WARN does not rehome pets — that is shelter directory.
  • A named animal with photo updates. Symbolic adoption is symbolic adoption; 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 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. 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 to Z. If you wanted a rescue shelter for dogs near you, stop and open shelter directory.

  2. 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. 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. 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 to 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 to Z. For extinct animals WARN has covered, use 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 editorial standards.
