Clue nest

Clue nests are nests that can be found while training Woodcutting or emptying bird houses on Fossil Island. Searching them will give players a clue scroll of the indicated difficulty, leaving an empty bird nest (excluding beginner clue nests). Like clue scrolls, players can only have one of each type of clue nest in their possession. Players can toggle whether or not to receive clue nests by speaking to Arthur the Clue Hunter in Lumbridge.

There are five types of clue nests:

Clues are not awarded if the player already has a clue of that tier.

Woodcutting rates

The chance of obtaining a clue nest depends mainly on the player's Woodcutting level together with the type of tree that is chopped, similar to how the drop rate of skilling pets is determined.^[1] In addition, the reward tiers unlocked by completing Combat Achievements grant a 5% boost to the drop rate of the corresponding clue tier, that is to say the easy, medium, hard, and elite clue nests.

Formula

Upon a successful skilling action, a roll is made for each clue tier one is eligible to receive (based on which types of clue are already owned) independently of the outcome of any of the other rolls.^[2] For each tier of clue nest, the following formula is used to determine its drop chance, whereupon a roll is made if the player is eligible.^[3]

The chance is $1$ in $\left\lfloor {\frac {\lfloor {\text{BaseChance}}\times {\text{CA}}\rfloor }{100+{\text{Woodcutting}}}}\times {\text{ClueTier}}\right\rfloor$

Where:

{\text{BaseChance}}=

The base chance of receiving a clue nest from a specific tree type. These are the same base chances that determine the drop rate of the beaver pet.

{\text{CA}}=

A multiplier of

0.95

if the corresponding reward tier of Combat Achievements has been unlocked, or

1

if it has not.

{\text{Woodcutting}}=

The player's visible

Woodcutting level. Visible boosts beyond level 99 are taken into account.^[4]

{\text{ClueTier}}=

The clue tier modifier applied at the end based on the type of clue that is rolled.

Base chance

The table below displays the base chance of obtaining a clue nest according to tree type.^[5]

Tree	Chance
Achey trees	317,647
Normal trees	317,647
Oak trees	361,146
Willow trees	289,286
Teak trees	264,336
Juniper trees	360,000
Maple trees	221,918
Hollow trees	214,367
Mahogany trees	220,623
Arctic pine trees	145,758
Yew trees	145,013
Sulliusceps	343,000
Magic trees	72,321
Redwood trees	72,321

Clue tier

The following modifiers are applied to the denominator of the drop chance, depending on the type of clue for which a roll attempt is made.^[6]

Clue tier		Modifier
	Beginner	0.2
	Easy	1.7
	Medium	2
	Hard	3.3
	Elite	10

Other factors

Equipping a ring of wealth (i) will double the rate at which clue nests are dropped while chopping trees in the Wilderness.^[7]

The 10% uplift in the drop rate of bird nests granted by the Woodcutting cape does not apply to clue nests.^[8]

Birdhouse rates

This article or section is incomplete and could do with improvement.

Reason: Birdhouse clue nest mechanics are not confirmed and any rates we have are rough estimates.
You can discuss this issue on the talk page or edit this article to improve it.

The chance of getting a clue, ring, egg, or empty nest from bird house trapping depends on the tier of birdhouse and the player's Hunter level (seed nests only depend on Hunter level). When collecting loot, 10 rolls are performed with a chance of providing these nests. It is possible to obtain multiple clues from the same birdhouse in a single one of these 10 rolls, but once at least one clue has been awarded, further rolls do not attempt to give clues.

[[{{#explode:22 June 2022\| \|0}} {{#explode:22 June 2022\| \|1}}]] [[{{#explode:22 June 2022\| \|2}}]] (update)	All birds' nests now despawn after 2 minutes instead of 30 seconds.
[[{{#explode:21 July 2021\| \|0}} {{#explode:21 July 2021\| \|1}}]] [[{{#explode:21 July 2021\| \|2}}]] (update)	Clue nest rates are now affected by completion of Combat Achievements. Clue nests no longer roll to determine which tier of clue you get after the initial roll to give you a clue nest.
