You're going to need more explanation or code. Is it a side scroller? If so do you move up?

EDIT: Also important, is it grid based or free moving?

This is my code... i need to get random birds drop down and kill them if they have position Y 400.

The birds are always on the same x but i need to get them random line a:

But the Brown birds always come together but i need to fix it random

int variabele1;
int variabele2;
float y2;
float y=1;
float speed=3;
float speed2=2;
float speed3=2;
float x2;
float spawn;
float nieuweRandom;
float nieuweRandom2;
float x3;
float y3;
import gifAnimation.*;
PImage[] animation;
Gif loopingGif;
Gif nonLoopingGif;
PImage[] animation2;
Gif loopingGif2;
Gif nonLoopingGif2;
void setup() {
size(400, 400);
frameRate(25);
smooth();
oscP5 = new OscP5(this,"239.0.0.1",7777);
// FGIF instelleningen voor volgen
loopingGif = new Gif(this, "player_bird.gif");
loopingGif.loop();
// nonLoopingGif = new Gif(this, "player_bird.gif");
// nonLoopingGif.play();
// nonLoopingGif.ignoreRepeat();
// P image Array
//animation = Gif.getPImages(this, "player_bird.gif");
// FGIF instelleningen voor volgen
loopingGif2 = new Gif(this, "evil_bird.gif");
loopingGif2.loop();
// nonLoopingGif2 = new Gif(this, "evil_bird.gif");
// nonLoopingGif2.play();
// nonLoopingGif2.ignoreRepeat();
// P image Array
// animation2 = Gif.getPImages(this, "evil_bird.gif");
}
void draw() {
nieuweRandom = random(400);
nieuweRandom2 = random(400);
// println(loopingGif.x);
background(40,158,224);
//x2 = random(400);
//uncomment dit voor te testen. variabele1 en 2 hangen dan aan de muiscoordinaten vast
//als de server draait, comment je deze terug.
variabele1 = mouseX;
variabele2 = mouseY;
//speed berekening
if (y<width) {
y = y + speed;
}
//speed berekening
if (y2<width) {
y2 = y2 + speed2;
}
//speed berekening
if (y3<width) {
y3 = y3 + speed3;
}
// dit is de wolk.
PImage d;
d = loadImage("cloud2.png");
image(d, x2, y2);
if(y2 >= height){
x2 = nieuweRandom;
y2 = 0;
}
// dit is de wolk.
PImage c;
c = loadImage("cloud.png");
image(c, x3, y3);
if(y3 >= height){
x3 = nieuweRandom2;
y3 = 0;
}
//Dit is de evil vogel
image(loopingGif2, 100, y);
//Dit is de player vogel
image(loopingGif, mouseX, 350);
}

Don't use loadImage in draw()! Load the images in setup().
Don't use random(400). Use random(width) or random(height), so it adapts if you change the dimensions of the sketch;

How the birds are spawn? At regular intervals? When a bird is killed? Upon user action?
You draw then draw a bird at a x position (I suppose that's x that varies) that is random along the width of the sketch. If you have several birds, you need arrays of positions.
