Play all 81 EE birds.

There is a button [BIRDS] on the main screen that brings up a list the birds played. This can be filtered by just European Expansion with the controls on the bottom. To satisfy the condition, keep a list of the European Birds in Notepad, Word, Excel, etc. and then mark off the ones as you play them so that when missing ones appear they can be taken and played. This achievement isn't difficult, just time consuming.

Play a game in which you score 180 points.

To achieve this requires a bit of creativity. One way is to create a local 4 player human game, controlling all 4 players.

One player is the 'max score' player. One player is the generate food engine, one player is the generate eggs engine and one player is the generate cards engine.

In the example below, a score of 181 was achieved:

• 59 Birds
  
• 25 Bonus
  
• 20 End of Round Goals
  
• 40 Eggs
  
• 21 Food on Cards
  
• 16 Tucked Cards

Player 1 (food engine) had the following birds in the grasslands:

• Bluethroat {Choose a food type. All players gain 1 of that food from the supply}
  
• Common Nightingale {Choose a food type. All players gain 1 of that food from the supply}
  
• Eastern Phoebe {All players gain 1 worm from the supply}

Each turn, a cube in the grasslands would generate 1 worm and 2 any food for the main player.

Player 2 (egg engine) had a Pileated Woodpecker {All players lay 1 egg on any hole nest bird. P2 may lay an additional egg on an additional hole nest bird}
This engine certainly could stand some improvement

Player 3 (card engine) had a Spotted Sandpiper in the wetlands {All players draw 1 card from the deck}
Again, this engine certainly could be improved

The main player's final flock was:

Forest

• Yellowhammer (2 / 3 egg / 1 tuck) {use all 4 actions, play another bird at EoR}
  
• Steller's Jay (5 / 2 egg / 1 tuck) {Gain 1 grain from the bird feeder, it may be cached on the card}
  
• Common Chaffinch (4 / 2 egg / 1 tuck) {choose 1-5 birds in this habitat and tuck one card from hand behind each}
  
• Spotted Owl (5 / 1 egg) {Draw 2 bonus cards, keep 1}
  
• Baltimore Oriole (9 / 2 egg) {All players gain 1 berry from the supply}

Grasslands

• Eurasian Magpie (1 / 3 egg / 5 food) {For each egg laying cube of another player, cache 1 food from supply on any birds.}
  
• Moltoni's Warbler (3 / 2 egg) {use all 4 actions, play another bird at EoR}
  
• Hooded Crow (3 / 2 egg / 13 tuck) {for each egg laying cube of another player, tuck one card from hand and draw that many cards.}
  
• House Wren (1 / 6 egg) {play another bird}
  
• Lazuli Bunting (4 / 4 egg ){All players lay an egg on a cup bird. Lay an additional egg on another cup bird.}

Wetlands

• Clark's Grebe (5 / 2 egg) {Draw 1 card / discard 1 card.}
  
• Great Crested Grebe (3 / 2 egg) {Draw 1 card for each empty card slot in this row. Keep one.}
  
• Forster's Tern (4 / 2 egg / 5 food) {Draw 1 card / discard 1 card.}
  
• Wood Stork (6 / 2 egg / 11 food) {Draw 2 bonus cards, keep 1}
  
• King Rail (4 / 6 egg) {Draw 2 bonus cards, keep 1}

Bonus cards:

• Historian - Birds named after a person {4 birds at 2 per bird = 8 points}
  
• Wildlife Gardener - Cup birds { 8 birds = 7 points}
  
• Wetland Scientist - Birds that can only live in water {5 birds = 7 points}
  
• Backyard Birder - Birds worth less than 4 points {6 birds = 3 points}

Careful management of end of round goals should yield 22 points.
It was quite helpful having 2 birds that (practically) gave one point per each egg laying action another player took. This resulted in 21 additional points in cached food and 13 additional points in tucked cards.

Bonus card birds are certainly key to closing the gap. And the example had some inefficiencies as well - a stronger egg laying engine for P2 might have resulted in an action or two in the forest resulting in an additional 6 points (5 tucked cards, one cached grain) per turn. The last bonus card draw was not optimal. The key here is that there are paths to 180. Good luck and good hunting!

Cache 15 food w/ predator powers.

As this requires maximizing your predate chances during the roll, food control is key. Therefore the best way to get this achievement is through the forest.

First off, strive to fill up the forest with birds that cache a food if the dice rolled outside the bird feeder come up with their specific food (birds marked with a skull and crossbones).

In the following example, the forest was:

• Ruby-Crowned Kinglet (play an additional bird)
  
• American Redstart (get an extra food)
  
• Eastern Screech Owl (Roll all dice outside and cache a rat if any are rat)
  
• Barn Owl (See ESO above)
  
• Northern Mockingbird (repeat a brown power).

In an ideal situation, the American Redstart would be in the 5th position, rather than the 2nd so that up to 4 cubes could always be pulled out of the birdfeeder before rolling for rats.

With the ability to pull up to 3 food with 5 birds in the forest (4 by spending a card or having a bird that pulls food from the feeder in the 5th position) the bird feeder can be reduced to 1 cube and 4 dice rolled each turn for 3 birds. Rolling at least one "6" on 4 dice is a 51.7% proposition - meaning given enough rolls, the necessary 15 food is statistically probable with 30 rolls (10 turns @ 3 rolls per turn).

Note: Food gathering can be cancelled (skipped) as soon as there is 1 food remaining in the bird feeder.

Birds that are helpful to this achievement are:

• Northern Mockingbird (1 fruit + 1 worm) [Any habitat] (Repeat a brown power)
  
• Gray Catbird (2 fruit + 1 worm) [Any habitat] (Repeat a brown power on one other bird in this habitat)
  
• Hooded Merganser (1 Fish + 1 worm) [Wetlands] (Repeat one predate power in the wetlands)

If going for a wetlands approach, the Northern Gannet (2 fish) allows as many fish rolled to be cached, so it allows for slightly better odds than any other bird that rolls for cached food - when combined with the Hooded Merganser, that could be attractive.

The forest seems to be the easier path because of the cube control and the birds tend to be cheaper.

Here is a list of all birds that satisfy the achievement goals sorted by habitat and (food costs):

• Forest:
  
  • Broad-Winded Hawk (rat)
    
  • Eastern Screech Owl (rat/worm)
    
  • Mississippi Kite (rat/worm)
    
  • Barn Owl (2 rat)
• Grasslands
  
  • Mississippi Kite (rat/worm)
    
  • Barn Owl (2 rat)
    
  • American Kestrel (rat+worm)
    
  • Burrowing Owl (rat+worm)
    
  • Ferruginous Hawk(2 rat)
• Wetlands
  
  • Snowy Egret (fish/worm)
    
  • Willet (fish/worm)
    
  • Barn Owl (2 rat)
    
  • Anhinga (2 fish)
    
  • Black Skimmer (2 fish)
    
  • Common Merganser (fish+any)
    
  • Northern Gannet (2 fish) (* caches all fish rolled that turn)
    
  • White-Face Ibis (1 fish+2 worm)

End the game with 0 eggs.

It is not required to win the game, just finish the game. Spending eggs is easy - play birds, get extra cards in the wetlands, activate birds that use eggs for other resources. Even playing a game with 26 actions of getting food or birds would do it.

Play 5 EE Birds in one habitat.

Just pay attention to what is coming up in the tray and pick a habitat.
Through normal play, getting 5 EE birds that live in the forest, grasslands or wetlands (many can be played in multiple habitats) is quite doable. The wetlands should be the easiest as that helps with seeing more cards to choose from.

Including the multi-habitat birds:
37 EE birds can live in the forest
39 EE birds can live in the grasslands
37 EE birds can live in the wetlands

Tuck 70 birds by the end of game.

This achievement requires the right birds and a decent Wetlands engine.

At first blush, those EE 'tuck up to 5 cards from deck for food' birds seem attractive, but they require a decent food engine to be useful (reducing the birds in hand available to tuck) - and they only activate at most 4 times each. As there are 4 rounds per game and 26 turns per game, this achievement is much easier using turn based (brown power) birds than round based (blue power) birds.

The Ruff, on the other hand, allows 3 tucked cards per round with no cost other than having the cards in hand, so it might be a decent complement if played in the first 2 rounds.

Set up a game with 4 robots on easy to increase the chances for free food, eggs and cards. This will also increase the amount of resources / other player actions available to use on activated powers.

The example below consists of 4 birds - all in the Wetlands:

• Mute Swan (tuck up to three cards from hand under 3 wetlands birds; draw one)
  
• Audouin's Gull (draw two cards; keep one, tuck one)
  
• Canada Goose (spend a grain, tuck two cards from deck)
  
• Common Nightingale (pick a food type, everyone gets one cube of that type).

With 4 birds in the wetlands, a typical turn was:

• Place a cube in the wetlands (draw 3 cards)
  
• The Nightingale produces a grain
  
• The Goose uses that grain to tuck 2 cards from the deck (2 tucked cards, 3 cards in hand).
  
• The Gull draws 2 cards - one to keep and one to tuck (3 tucked cards, 4 cards in hand).
  
• The Swan then tucks 3 cards from hand and draws one (6 tucked cards, 2 cards in hand).

So, at 6 tucked cards per turn, this engine tucks 66 cards in 11 turns (rounds 3 and 4) leaving rounds 1 and 2 to set this up and tuck the four odd cards required to achieve this goal.

In this example, 84 cards were tucked.

Notes for the following list:

• Some birds (@) require a food to activate. They should be placed in the wetlands earlier (activate later) than birds that can produce that food (@@).
  
• There are some birds that pull cubes out of the bird feeder, but this requires the right type of food (fish or grain) be present at the time of gathering food, so they are not being included.
  
• If using a 'spend an egg to get a food' bird (the Common Raven; American Crow; or Black Crowned Heron), place a 'tuck a card and lay an egg' bird after it so that an egg is generated before needing it to activate the food generation.
  
• (#) The Greater Flamingo is a feast or famine type of bird. It requires that other players have placed cubes in the wetlands - but it can be very powerful in the engine under the right circumstances (see the example in the "Full Tuck / Birdnado Take 2" section).

Useful birds to look out for (more or less ordered by attractiveness in each category):

• WHEN ACTIVATED (BROWN) (limited to birds that can live in the wetlands)
  
  • Birds that repeat a brown power
    
    • Northern Mockingbird
      
    • Gray Catbird

    • (up to 7) Greater Flamingo (For each cube in the wetlands for another player, tuck a card from hand and draw that many cards).
      
    • (up to 5) Common Chiffchaff (Tuck up to 5 birds from hand on each bird in the wetlands)
      
    • (up to 3) Mute Swan (Choose up to 3 birds in your wetlands, tuck a card from hand behind each one. Draw 1 card)
  • (@@)Food generation birds

    • Eurasian Collared-Dove (any food)
      
    • House Sparrow (grain)
      
    • Common Swift (worm)

  • Play on top of another bird and tuck that bird birds
    
    • Common Buzzard
      
    • Eurasian Hobby
      
    • Montagu's Harrier
      
    • Red Kite

Play 16 birds.

The key to this goal is the new mechanic "Play this bird on top of another bird for 0 cost".
You are looking for one of the following:

• Common Buzzard
  
• Eurasian Hobby
  
• Mantagu's Harrier
  
• Red Kite

You will also be on the look out for ways to play extra birds.
Birds that allow you to play an additional bird in a habitat at normal cost.

• Downy Woodpecker (forest)
  
• Red-Eyed Vireo (forest)
  
• Ruby-Crowned Kinglet (forest)
  
• Tufted Titmouse (forest)
  
• House Wren (forest/grasslands)
  
• Eastern Bluebird (grasslands)
  
• Mountain bluebird (grasslands)
  
• Savannah Sparrow (grasslands)
  
• Great Blue Heron (wetlands)
  
• Great Egret (wetlands)

Birds have the end of round (blue) power to play a bird at the end of each round if you played at least one cube in each action:

• Moultini's Warbler
  
• White wagtail
  
• Yellowhammer

Birds that allow you to play an additional bird in a habitat for a resource when activated (brown)

• The Common Moorhen allows for an additional wetland bird to be played at the cost of a food
  
• The Goldcrest allows you to play another bird in the forest for the cost of a card
  
• The Short-Toed Treecreeper allows for another bird in the forest for the cost of an egg

The key is to focus on cheap birds and avoid the 'play across two columns in a single habitat birds.
In the end you should be able to play one (or more) of the 4 'replacement birds' on your filled out mat.

Use 3 cards to pay for a bird.

Keep on the lookout for the Bonelli's Eagle or Eastern Imperial Eagle.

Once you have one of these birds, accumulate 3 cards to sacrifice and play either Eagle substituting the birds for food.

Steal 10 food from opponents.

There are five birds that allow you to steal food from an opponent.
Start the game with 5 players (you and 4 robots will do) so that there is sufficient food outstanding to steal.

In the Forest there are the Eurasian Jay (grain) and Little Owl (rat).
In the Grasslands there are the Little Owl (rat) and Red-Backed Shrike (worm)
In the Wetlands there are the Black-Headed Gull (any) and the Kingfisher (fish).

Of the 5 birds, the Black-Headed Gull is the most advantageous as it allows for a food of any type to be stolen.

Given enough food out there, 5 or so rounds of having 2 of these birds in any habitat should suffice in getting this achievement.

Play a bird on top of a smaller bird.

I do not know if this is buggy or it requires a specific set of circumstances - such as replacing an EE bird (or an original bird).

On the surface, this should be achieved by playing one of the 4 replacement birds:

• Common Buzzard (123)
  
• Eurasian Hobby (75)
  
• Montagu's Harrier (113)
  
• Red Kite (157)

on top of a smaller bird. I tried to get this achievement 5 or 6 times until it finally triggered.

Trigger 3 end of round (blue) powers in a round.

Keep an eye out for blue power birds. Of especial interest are the play an extra bird if all 4 actions are taken birds (Moltoni's Warbler, White Wagtail, Yellowhammer) as these can each be triggered off the same event (use all 4 actions in one round) resulting in a free bird play.

Here is a list of end of round birds and their triggers / actions:

• The European Honey Buzzard {Reset bird feeder at end of round. Gain all worms rolled.} will always trigger

Birds that depend solely on actions you control:

• Birds that trigger if a habitat has birds, but no eggs
  
  • Black Redstart
    
  • Lesser Whitethroat
• Birds that trigger if you have food in inventory
  
  • Common Starling (any food)
    
  • Common Swift (worms)
    
  • Eurasian Collared-Dove (any food)
    
  • House Sparrow (grain)
• Birds that trigger if you use all 4 actions in a round (play a bird, gain food, gain eggs, gain cards). Unclear if a bird to play and requisite food / egg costs are needed in inventory.
  
  • Moltoni's Warbler
    
  • White Wagtail
    
  • Yellowhammer
• The Ruff will trigger if you have at least one card to tuck.

Birds that have not too difficult trigger conditions:

• Birds that require that any player (including yourself) has a bird with a predator icon.
  
  • Carrion Crow
    
  • Griffon Vulture
• Birds that require that another player 'gains eggs' at least once during the round
  
  • Dunnock (requires that you also have at least one egg spot open)
    
  • Eurasian Magpie
    
  • Hooded Crow (requires that you have at least one card to tuck)
• The Common Goldeneye will trigger if you have at least one other cavity nest bird and an empty egg slot on the duck.

Birds that count double towards end-of-round goal conditions (but can be confusing as to what goals trigger):

• Cetti's Warbler
  
• Eurasian Green Woodpecker
  
• Greylag Goose

In the following game, an early Greater Flamingo (with Gray Catbird) playing local 5 human (solitaire) yielded a score of 213 - 164 in tucked cards (98 of those under the Greater Flamingo).

Final score:

• (27) Birds
  
• (3) Bonus cards {Birds with a food cost of 3 (3 birds = 3 points)}
  
• (12) End of Round Goals
  
• (7) Eggs
  
• (164) Tucked Cards
  
• (213) Total

P1: (Grasslands) Lazuli Bunting {All players lay 1 egg on any cup nest bird}
P2: (Wetlands) Northern Shoveler {All players draw 1 card from the deck}
P3: (Wetlands) Eastern Phoebe{All players gain 1 worm from the supply} and Osprey {All players gain 1 fish from the supply}
P4: (Wetlands) Sandhill Crane{Discard 1 grain to tuck 2 cards from this deck behind this bird.}

The high score player (P5) had the following by the end of game:
Forest: Empty
Grasslands:

• (1)Snow Bunting (5 /1 tucked card) {When another player tucks a card for any reason, tuck 1 card from your hand behind this bird, then draw 1 card at the end of their turn}
  
• Ruff (2 / 1 egg / 12 tucked cards){At End of Round, tuck up to 3 cards from your hand behind this bird. Draw 1 card for each card you tucked}

Wetlands:

• Greater Flamingo (3 / 98 tucked cards) {Choose 1 other player. For each action cube on their wetland, tuck 1 card from your hand behind this bird, then draw an equal number of cards.}
  
• Gray Catbird (5/1 egg / 6 tucked cards) {Repeat a brown power on one other bird this habitat.} [Cup nest, 3 capacity]
  
• American White Pelican (5 / 28 tucked cards) {Discard 1 fish to tuck 2 cards from the deck behind this bird.
  
• House Finch (3 / 5 eggs / 13 tucked cards) {Tuck a card from your hand behind this bird. If you do, draw 1 card.} [Cup nest, 6 capacity]
  
• Mute Swan (4 / 6 tucked cards) {Choose 1-3 birds in your wetlands, tuck 1 from your hand behind each. If you tuck at least 1 card, draw 1 card}

(1)The Snow Bunting was intended to tuck more cards from the Sandhill Crane's action, but there wasn't enough grain in the game to trigger the Crane's tucking.

In general,

• P1 supplied the eggs to use for playing birds.
  
• P2 served both a 'gain a card for tucking' as well as generating wetlands cube actions role.
  
• P3 supplied the fish for the American White Pelican to trigger as well as allowed for a building of a worm reserve to pay for played birds.
  
• P4 didn't factor into the overall strategy.

The Greater Flamingo + repeat served as a great combination (and as the power is tuck then draw the same number of cards, the available cards kept replenishing). The key here is to use the first turn (or two) of each round to play additional birds, so that the later turns of each round can be used to maximize the Greater Flamingo's power.
