I have found 9-pound bags of a mix of mostly millet with some sunflower seed and, I think, safflower seed, at a dollar-type store here called Big Lots. $7 per bag. Birds gobble it up in winter, but in the winter they'll eat anything; in the spring they are picky, kicking out the milo for the pigeons and doves, so I stop feeding them and concentrate on hummingbirds and, this year, suet for Ladderback and Downy woodpeckers. Also I have nyger thistle feeders (both metal mesh feeder and sock feeder) out for our sweet, tiny lesser goldfinches. To complete my first post in this forum, I spotted and got pictures of a male Northern Cardinal this morning, a rare sighting for our area (Albuquerque). A similar male bird (the same one??) was reported a few miles further north back in February. I also photographed a rare Vermillion Flycatcher in April. Maybe more birds are moving into my state -- and I'll have figure out how to feed them if they visit my apartment complex :)

I'm glad your bird problem turned out to be seasonal but just in case you ever face this problem again (or any bird infestation problem) I thought it might be helpful to just mention a different angle on this. The problem is not that the birds are pooping (or whatever they're doing) in your pool. That is simply a symptom of your real problem: that your environment is attractive to birds. If you really want to keep birds from being destructive to your property you have to make it so that your land is a place they don't want to hang out on in the first place. There are a lot of different approaches to this but yes, stopping the food supply is one of them. Another would be the mylar balloons someone else mentioned up above. There are also specialized bird scare balloons with 'eyes' that follow the birds wherever they fly as well as holographic tape. These incorporate movement so they are usually more affective than static decoys. There are other senses to attack as well: taste/smell, touch, and hearing. Birds hate methyl anthranilate (a chemical derived from concord grapes that has long been used for grape flavoring)--it gives them a similar sensation to what we feel when we encounter bleach. This comes in commercially available sprays. Also, there are sticky gels, netting, or spike strips that keep birds from roosting on certain surfaces. Lastly, there are sound devices that utilize recordings of predators/distress calls that scare birds away. For a partially or fully enclosed area you could use an ultrasonic device as well (one that can't be heard by humans but is annoying to birds and bats). Make sure that you switch up whatever you use from time to time. If you use balloons, move the location (but always keep it near where the birds are nesting). If you're using a sound device change the interval between effects, try to randomize the effects being used. Also, using the products together in a synergistic way will create a more effective and longer-lasting reaction. I'm glad to hear that no one has mentioned killing or injuring the birds...don't do that. As mentioned before that would be reacting to the symptoms rather than truly solving the problem. Furthermore, it would be very easy to accidentally tamper with one of the MANY birds protected by the Migratory Bird Act of 1918 (and then you'd be in big trouble). Just a side note: be careful when cleaning up the bird poop. Birds can transmit over 60 diseases to humans. Some of them are fatal. Bird dropping particles can be unknowingly inhaled and lead to serious health problems. Good luck in your future bird encounters!

A standing birdbath on the patio has gotten only limited use for several years. Also far from the house and a pain to keep clean. This year I bought one of those deck-railing birdbaths. It's only steps from the kitchen so easy to keep clean in hot weather, and it's being used for both drinking and baths. The red-headed sparrows that drink from the ant cups unfortunately still use the ant cups as well as the birdbath. Well who wouldn't like to have two sources of water? :) I thought a brick too high so used a small flagstone type stone and a couple of 3-4 inch river rocks in the middle. However, they drink from the edge.

If the small bird had a true crest, an oak titmouse perhaps. Scrub Jays don't migrate, but they can shift about a bit within their range between winter and summer months. Inland, they are more likely to be found in a lower mountain shrubs and oaks type of habitat, rather than flat expanses of farmland.
