No Comparison

     Many people left off last year with a garden full of hummingbirds, and are fully expecting that many more to return this Spring. There are so many differences from springtime to late summer or autumn. There are so many factors and variables involved that simply don't allow us to compare the two seasons.
     First of all, springtime has all the mature birds, and their purpose is very different. In spring time they've got a purpose of breeding, and nothing will interfere with that. They won't congregate in yards unless they're migrating through. They are very territorial because they want the breeding rights. Later in summer, during the southern migration, they do congregate, but with a little less intensity and anger, and I mean just a little bit less. They still do and will always have fire in their tail feathers. 
     We always start off with a certain number of hummingbirds in springtime and then we end up with nearly double that later in summer. Sadly many of those young birds won't make it till the next spring, but the rest will, and they will be looking for a new breeding ground of their own.
​     Over years of research I tracked the number of sightings every day from the time they arrived in Spring to the time they Departed in late summer, and the results just simply can't be compared. The largest numbers of sightings I recorded in Spring were only 200 to 300 per day. The numbers in late summer when all of the birds including adult males, adult females and juveniles are trying to feed and fatten up for the migration, are somewhere between 2 and 12 thousand per day. This is an increase of more than 10 times. It doesn't mean there are 10 times the number of birds, but rather all of them have a different purpose than in springtime, and that purpose is to feed as much as possible and head south with a fat belly. 
     So ultimately what I'm trying to say is that the numbers in springtime have very little in common with late summer. If you have one or two regular birds hanging around in Spring, or they only show up once a day or even less, don't be alarmed. They've got other things in mind, and food is much lower on their priority list.
