Hygiene in the heat

What is changing this month

Heat is the main risk now: seed and sugar water spoil faster, and crowded feeders concentrate birds when disease spreads most easily.

Birds to expect in July

Most often reported at feeders this month. What turns up depends on your region and the weather, so treat it as a starting point.

Feeder jobs for July

• Clean seed feeders weekly and nectar feeders every couple of days.
• Move the bath into shade if you can.
• Watch for sick birds and disinfect if you see symptoms.

Water in July

Shade keeps bath water cooler and birds use it more. Refresh daily and scrub out algae weekly.

What to watch for

• Heat speeds spoilage. Clean seed feeders weekly and nectar feeders every couple of days.
• Provide shade and water; a bath in shade stays cooler and is used more.
• Watch for sick birds at crowded feeders and disinfect if you see symptoms.
• If you cannot keep up with cleaning, feed less rather than feeding dirty.

Three things not to do

• Don't feed ordinary suet in heat unless it is formulated for warm weather.
• Don't let a crowded feeder go unwashed; warm weather speeds disease spread.
• Don't ignore a sick bird — clean, disinfect, and consider a temporary pause.

Check this locally

Timing shifts with latitude, elevation and the year. Use these as pointers, then check what is actually happening near you.

• North: nesting is at its height; feeders are secondary to insects.
• Mid-latitudes: heat and humidity make hygiene the main job.
• South: water and shade matter more than any seed.
