Rufous-tailed Hummingbird (Amazilia tzacatl) This is a common species around Arenal - this one was recorded at La Fortuna (Costa Rica).

Here's another example of the Rufous-tailed Hummingbird (Amazilia tzacatl) trill. (Costa Rica)

This is the"feeding call" of a Rufous-tailed Hummingbird (Amazilia tzacatl) at a Heliconia flower at El Gavilan lodge, Puerto Viejo de Sarapiqui (Costa Rica), 6/18/99.

Three female Black-Chinned Hummingbirds (Archilochus alexandri) "argue" over who gets to use which station at the feeder. Recorded 6/14/97 in my back yard.

A male Black-Chinned Hummingbird (Archilochus alexandri) vocalizes as he feeds. Note the sound of the "hum" from his wings. Analysis of this hum indicates his wingbeat frequency is 51 beats per second!

While Anna's feeds, he chips this characteristic call during his meal.

This male Anna's Hummingbird (Calypte anna) "sings" while perched in a Juniper in Sedona, Arizona. This is a song which is very difficult to record and edit, since it is very low volume and tends to get lost in whatever background noise there is. The vocalization is highly modulated and sounds quite like distant human speech, quite unlike any other hummer I've heard. One must be right under the bird to catch his squeaky, scratchy, croaky sound.

The wingbeat of the Anna's is slower than most, which is logical, since they're one of the largest hummers normally north of Mexico. This one measures only 45 BPS!

Violet Sabrewing on Lek (Campylopterus hemileucurus) - This sparrow-sized bird is one of the largest Hummers, and one of the most beautiful. This male was recorded on his "Lek". A Lek is a place where males of a species gather to display their wares to the available females in the area. It is usually a small area where several (10 or so in this case) males are within sight and earshot of each other. Leks can be found by listening for continuous calling coming from several birds of the same species. This was recorded in early June. (Costa Rica)

Lesser Nighthawks (Chordeiles acutipennis) sit on the ground of the chaparral hilltops and trill this toad-like trill on the summer nights around central Arizona. This one was at Peck's Lake [Arizona] May 20th, 1999. The sound is very hard to localize, since it is so low, quiet and "generic" (high-pitched sounds are much easier to find), and they are generally closer to you than they seem to be.

This species gets together in a kind of lek - several calling at once, and occasionally flying up in a fluttering courtship display while singing this strange song. 06

Here's a different "finish" to the regular trill for those of you who enjoy Nighthawk talk.

A Common Pauraque (Nyctidromus albicollis) calls in the early evening at the "El Pizote" in Puerto Viejo de Talamanca (Costa Rica), 6/22/99, 5:40 PM. I had seen this guy earlier that morning, as I walked near his ground roost in a derelict cacao plantation. He apparently never strayed far from that spot, as these recordings were made 12 hours later only a few meters from where I had spotted him.

Little Hermit (Phaethornis longuemareus) male on lek (A Lek is a place where males of a species gather to display their wares to the available females in the area) in Manuel Antonio (Costa Rica), 6/15/98. These birds, when on lek, are almost impossible to see. They sit very near the ground in dense understory. I sometimes had to sit for 15 minutes, knowing I was only 3 meters away from them, before I saw one.

Long-tailed Hermits (Phaethornis superciliosus) lek (A Lek is a place where males of a species gather to display their wares to the available females in the area.), as do Little Hermits. This sample is a male on lek in Carara Biological Preserve. The lek was approximately 30x100 meters and held 8-10 males.

In the summer Common Poorwills call from the hillsides in the southwest US. They are best spotted by driving slowly along the dirt roads in their territory at night, since they like to sit on roads for some reason - they flutter up in front of the lights when you get too close. This one was on the slopes above Peck's Lake [Arizona], 5/19/99, just after sunset.

The Broadtail Hummingbirds (Selasphorus platycercus) arrive at this altitude (3500ft, 1065M) in mid August. Until now they've stayed up in the mountains which surround our Verde Valley [Arizona], preferring the cool pines to the mesquite scrub in the hottest parts of the Summer. In this sample you hear a male's characteristic (and identifying) wing trill, which sounds like a coach's whistle. He's also vocalizing, which you'll hear as "cheeps" amid the wing noise. His wingbeat averages 45 bps while feeding, 51 bps while being chased from the feeder.C94

Listen carefully for the wing trill of this male Rufous Hummingbird (Selasphorus rufus). It's an identifying feature, as is his constant chatter while he feeds. Wingbeat analysis indicates a wingbeat of 62-65 bps in this sample.

A young male Rufous Hummingbird (Selasphorus rufus) has established a territory at my feeders. He announces that he's "taken over" by continually chattering this one-note warning. When another hummer of any species enters his airspace, he "bounces" them by rushing at them and emitting the high-pitched warning beeps you hear near the end of this sample! Attentive listeners will hear a Flicker in the distance on the first sample.

If intruders ignore his one-note warning, a male gets more aggressive and challenges them with a severe tongue lashing ! This routine is so effective that after a few days, virtually no other hummers come into his area and all he needs to do to maintain it is sing his one-note samba. Rufous hummers are both aggressive and intolerant of other species at the feeder. His wingbeat here measures a fairly fast 60 bps.

Chestnut-collared Swifts (Streptoprocne rutila) - These were flying high and fast near Fortuna Falls (Costa Rica), talking all the time.

A Band-tailed Barbthroat (Threnetes ruckeri) sits high above our heads in a tree and calls for long stretches at Guayabo Nat'l Park, 6/25/99.
