Recent Birds at Rio Bosque

 

Here are some of the more noteworthy birds found at the park in the past month. 


Winter residents are starting to appear.  Approximately 250 ducks are now present.  The first Northern Flicker appeared 19 Sep; the first White-crowned Sparrow, 20 Sep. 

 

Water deliveries to the park from the Roberto Bustamante Wastewater Treatment Plant resumed 1 May.  Portions of the wetland cells are flooded.  Soras are present at both wetland cells and can often be heard calling.       

 

A single White-tailed Kite had been consistently present on the east side of Wetland Cell 1 throughout August.  On 26 Aug, it was joined by a second adult bird.  Now, we know the second adult was the female, finally able to leave a well-hidden nest as the nestlings grew.  On 14 Sep, the first young bird left the nest and perched uncertainly atop a low Goodding willow nearby.  Harris's Hawks continue to be seen regularly.  Swainson's Hawks are only being seen sporadically. 

All three of the park's Wood Duck nest boxes currently have resident Western Screech-Owls.   With the nesting season over, Burrowing Owls are again getting hard to find.  Look for them on the mounds with burrows that are scattered throughout the park.
