Haber Subjunctive

One of the questions testing the present subjunctive of haber is:

Los pájaros irán donde ________comida.

With the correct answer being haya.

I understand the subjunctive being used in cases of hope, desire etc but I don't understand why it is used in this case rather than 'hay'.

Thanks.

Hola Martin

When we there is no certainty we use the subjunctive. I could use both the indicative and the subjunctive here:

Los pájaros irán donde HAY comida. 

In this case, the speaker know that the birds are going to a place where [he knows for sure] there is food. (certainty= indicative)

Los pájaros irán donde HAYA comida. 

Here, using the subjunctive, we need to assume that the speaker doesn't know whether there is or not food in that place. There is no certainty. 

I hope this helps,

Inma

Thanks Inma. That explains it perfectly. I was thinking only of the first case where there was certainty of food being there.
