A large garden spider in Australia is recorded consuming a finch. From the Telegraph.co.uk:

Mr Shakepeare said he had seen Golden Orb Weaver spiders as big as a human hand but the northern species in tropical areas were known to grow larger.

Queensland Museum identified the bird as a native finch called the Chestnut-breasted Mannikin.

“It wouldn’t eat the whole bird,” he said.

“It uses its venom to break down the bird for eating and what it leaves is a food parcel,” he said.

Greg Czechura from Queensland Museum said cases of the Golden Orb Weaver eating small birds were “well known but rare”.

I’ve never seen a spider capture and eat a bird, but I have observed a spider consume a fairly large day gecko in Madagascar. While living in Madagascar as a Peace Corps volunteer, I woke up around five o’clock in the morning, walked outside with a candle, and as I went to grab the door to my pit toilet, I saw a huge spider consuming a day gecko.
