List of birdwatchers

List of birdwatchers is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of birdwatchers rather than just read about it. In short: This is a list of notable birdwatchers and of people who are notable in their own right but also happen to be birdwatchers. First are listed birdwatchers with large life lists, which is based on the number of species of birds each of them has/had seen.

Key takeaways

List of birdwatchers belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of birdwatchers to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of birdwatchers from memory before moving on to harder problems.

Reference excerpt

This is a list of notable birdwatchers and of people who are notable in their own right but also happen to be birdwatchers. First are listed birdwatchers with large life lists, which is based on the number of species of birds each of them has/had seen. Depending on the taxonomic viewpoint, there are 10,858 (Clements V2023) or 11,032 (IOC ver. 14.1) living bird species recognised.

Large life lists

As of January 5th 2026 according to the iGoTerra website, there is only one birder who has added 10,000 or more species of birds to their life lists. An additional 18 birders have added at least 9,000 species of life birds and 34 at least 8,000 species. Note: all known sources of bird species life list data are self-reported. Birders with over 8,000 species include:

Peter Kaestner: 10,002 / 10,009 / 9,851 (#1 on Surfbirds / #1 on iGoTerra / #1 on eBird). Discovered the Cundinamarca antpitta (Grallaria kaestneri), which was subsequently named after him. First birder to see a representative of each of the world's (currently 249 [2021 eBird/Clements list] or 253 [2024 IOC list]) bird families. Philip Rostron: 9,763 (#2 on Surfbirds) Claes-Göran Cederlund: 9,761/ 9,829 (#3 on Surfbirds, #4 on iGoTerra). Deceased 2020) Sue Williamson: 9,306 (#14 on Surfbirds—#1 female birder) Phoebe Snetsinger: 8,398 (deceased 1999). First person to see 8,000 species. At time of her death in Madagascar she was World #1. Bernard Master: 8,346 The Chocó vireo (Vireo masteri) is named after him.

Worked examples

Example 1 — a first encounter with List of birdwatchers

Start with the simplest possible case. Write down what List of birdwatchers claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of birdwatchers before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of birdwatchers ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of birdwatchers

In research: List of birdwatchers appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of birdwatchers in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of birdwatchers is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birdwatchers, Lists of people by activity, Lists of people by occupation, so understanding it makes those chapters shorter.
In everyday life: Look for List of birdwatchers outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
