Three Weeks and Counting Down

Although Sibley's Guide to Bird Life and Behavior fails to note the incubation period for Burrowing Owl eggs specifically, the guide and my most recent observations seem to indicate that there may be fledglings at the burrows within a few weeks.

The Burrowing Owl above was photographed at Cape Coral Library in April 2010.

Sibley notes smaller owls to have the shorter incubation period while the largest owls have incubation periods of up to five weeks.

I was able to make four trips to Cape Coral to observe the Burrowing Owl since my last post and also made a trip to Harns Marsh Preserve in Lehigh Acres.

The Burrowing Owl above was photographed at Cape Coral Library in April 2010.

My speculation of the timing for the hatching of the owls is based on what appears to be strong evidence.

Every single burrow observed along a residential street parallel to Skyline Boulevard south of the Cape Coral Library had a sole owl at the entrance to the burrow on the evening of 8 April 2010.

Just days before, in most cases, both owls were observed at the burrows so there's the possibility that the females have most recently been in the burrows laying and incubating eggs.

My research of the Burrowing Owl has led to the understanding that owls will typically lay one egg every day or two in favorable conditions of food availability (thus far I have only observed food consumption on two occasions) and lay up to five eggs.

I've found the Burrowing Owl sex to be extremely difficult to distinguish as the bird's appearance is so similar.

There was a pair of owls I observed on Wednesday at the Cape Coral Library where one of the bird's breast was significantly whiter than the other.

The birds mated and, with a close look at the photographs taken, I will be able to determine which of the two was making enhancements to the burrow by digging at its entrance which I observed for the first time.

I am quite confidant to note in my study of the Burrowing Owl that the male stays at the entrance of the burrow while the female will sometimes leave it briefly prior to sunset.

Under such occasions where the female leaves the burrow entrance, she most often returns at the bequest of the male with his call where mating has often been observed immediately thereafter.

There is a burrow south of the Cape Coral Library that still does not have the PVC pipe installed to indicate its presence.

While I considered immediately reporting the burrow and its owl activity when found, I am glad now in hindsight that I had not.

A story has been told to me by my work acquaintance Stephanie Sikora that Burrowing Owls that were active at a Publix Super Market on Cape Coral Boulevard abandoned the burrow when protective measures were put in place.

Although I've spent quite a few hours observing the owls at this particular burrow south of the library, I have not observed them to mate which I cannot explain more than unusual.

There were several mating events again observed in lighting conditions too dark to photograph.

This past week also offered me the opportunity to photograph the Swallow-tailed Kite for the first time at Harns Marsh Preserve.

While I had observed the kite in the area of the Southwest Florida International Airport on several occasions late last fall and most recently this past week as well, I didn't have my camera with me.

There were numerous waterfowl at close range at Harns Marsh Preserve including several species.

A highlight in their sighting was the Common Moorhen which involved a chase as I've observed once before at Green Cay Wetlands and Nature Center near Delray Beach.

Although I didn't see the Snail Kite at Harns Marsh on this week's visit, it was reported to have been observed that morning by a fellow visitor and world travel I met named Hemant Kishan.

I also met other interesting people including the mother (recovering from a broken ankle yet insisting on walking a great distance at Harns Marsh Preserve) of the Chairman of the Wildlife, Ecology and Conservation department, John P. Hayes, at the University of Florida.

The wildlife enthusiasts above were photographed at Harns Marsh Preserve in April 2010.

I encountered Cheryl, Gloria and Wes as well visiting from Venice, Florida, where I was told of some extraordinary bird activity and recovery around the Venice Rookery.

Linda from Michigan was also a pleasure to speak with as she told me of a seasonal wildlife photographer that has studied the Scarlet Ibis with great success and most recently reported to have been observed at Little Estero Island Lagoon.

Certainly off the subject of wildlife though in fitting with the title of this blog entry, I want to note that I witnessed the launch of the Space Shuttle Discovery on the morning of 5 April 2010 from Fort Myers.

It was quite extraordinary as the light from the shuttle's engines was comparable to the brightest anti-collision lights of large commercial aircraft flying overhead at night toward the above mentioned airport.

Although I didn't photograph this event, it will always be a fond memory, and may be seen as witnessed in close proximity to Cape Canaveral by pbaser and blogger Tim Rucci.

Feature: Wakodahatchee Wetlands

A three-quarter mile long boardwalk with rain shelters meanders through different man-made habitat types at a facility known as Wakodahatchee Wetlands which is designed to naturally filter highly treated wastewater in southern Delray Beach, Florida.

The scene above was photographed at Wakodahatchee Wetlands in February 2010.

A very large alligator was observed in my February 2010 visit which is a testament to the successful feeding it has on the birds and mammals that have been attracted to Wakodahatchee.

The gator was interesting to watch in its apparent stealth to take down a Green Heron while the bird was brazen on a patch of land it seemed very comfortable on.

The alligator above was photographed at Wakodahatchee Wetlands in February 2010.

A juvenile alligator was observed during my February 2009 visit.

The five different habitats created on former agricultural land adjacent to the Palm Beach County Water Utilities Department Southern Region Water Reclamation Facility has resulted in excess of 150 bird species seen thus far by wildlife enthusiasts.

The Cattle Egret above was photographed at Wakodahatchee Wetlands in February 2009.

The majority of the birds are migratory species that should not be expected to be seen year round or even at certain times.

Such an example is the Black-bellied Whistling Duck which I had the great fortune to see in my 2010 winter visit to Wakodahatchee which was not seen in 2009.

The Black-bellied Whistling Duck above was photographed at Wakodahatchee Wetlands in February 2010.

The 2010 sighting more than made up for it as the dozen or so ducks in the group that inexplicably took flight and strafed me for a memorable experience.

Between the two visits, there was a give and take with species seen.

The Double-crested Cormorant and juveniles above were photographed at Wakodahatchee Wetlands in February 2010.

The very attractive Hooded Merganser was pleasantly seen in the same spot I had observed the species on both visits.

The male disappointingly did not show off his crest on my most recent visit.

The Hooded Merganser above was photographed at Wakodahatchee Wetlands in February 2009.

The Wood Stork, a bird species of special concern, was observed at Wakodahatchee in 2010 with about a dozen solitary individuals seen along Alligator Alley on the way back home to Florida's west coast.

Courtship behavior of the Great Blue Heron was not observed in 2010 as it had been in 2009.

There were a number of nests observed that had Anhinga and Double-crested Cormorant juveniles begging for food from their parents on both visits.

This venue is very popular with visitors that are quite disruptive for wildlife photography when using a tripod as the boardwalk shudders with almost every step even from a great distance.

A similar must see venue within the Whistling-Duck and Wetlands Cluster of the Great Florida Birding Trail on a much larger scale is Green Cay Wetlands a short drive to the west.
