Where do purple martins nest in Texas?
As elsewhere east of the Rocky Mountains, Purple Martins in Texas have abandoned their ancestral habit of nesting in natural cavities (Hill 1992, Hill 1993); they breed almost exclusively in backyard birdhouses (Brown 1997).
When do purple martins come back to Texas?
Life History The Purple Martin is one of the earliest neotropical migratory birds to return to the United States each year. After spending approximately five months in South America, Purple Martins make their appearance in Texas during the first half of February (Figure 5). Sometimes individuals arrive as early as January.
Where do purple martins migrate to?
Purple Martins are among the first birds to return to the States during spring migration. Clumps of martins depart from South America and make their way to the East Coast, where they settle into human-made nest boxes.
Where do purple martins live in Arizona?
For exam- ple, Purple Martins can be found nesting in the Sonoran desert of Arizona, where surface water is scarce, but cavities in saguaro and organ pipe cacti are abundant. They also occupy areas in the nearly treeless High Plains where they would otherwise be absent, if not for housing supplied by humans.
Where are the Purple Martins now?
Purple Martins migrate to South America for the winter, but before leaving, they may gather to roost in groups of thousands in late summer. Has declined seriously in parts of the west, and currently declining in the east.
When should I expect my Purple Martins?
Purple Martins are probably leisurely migrants that fly only during the day and forage as they go. Nonetheless, they are one of the earliest South American migrants to arrive in the spring, reaching Florida as early as mid-January and New England in mid-April.
How long do Purple Martins stay in South Texas?
16-22 weeksSEASONAL OCCURRENCE: The spring arrival of Purple Martins typically begins in mid-January through early February in South Texas, while they may not appear in northern areas of the Panhandle until late March (Ray 2001). Arrivals typically continue at individual colonies for 16-22 weeks (Hill 2001).
Are the Purple Martins still in Austin?
Although they have roosted in Austin every summer for several years, the expected flock failed to arrive at its usual spot near the Austin Community College's Highland campus in 2018, leading enthusiasts on a hunt for half a million missing birds.
When can you put up purple martin houses in Texas?
Wait until about four weeks after the first Martins have arrived in the area to open your housing. It's important to not open your house too soon. Otherwise, European Starlings and House Sparrows will take over the nesting compartments and prevent Martins from colonizing.
Do House martins return to the same nest each year?
Did you know? House martins will return from their African wintering grounds to the same nesting sites each year. They can reuse their old nests, saving them about ten days' work collecting mud.
How do I keep sparrows out of my purple martin house?
Here are some easy ways to keep sparrows out of your newly-built purple martin house:Monitor and Eliminate Their Nesting Sites.Offer a Lot of Cheap Bird Food.Install a Sparrow Excluder.Use Traps.Offer Suet Without the Seeds.Consider Preformed Seed Shapes.Use a Halo Baffle to Protect Sunflower Seeds.More items...•
Will purple martins run off other birds?
They bother the martins by continually running them off and if the martins do get to lay eggs, both of these birds will go from compartment to compartment, destroying the eggs and young and taking over the nesting cavities.
How high should a purple martin house be off the ground?
12-20 ftMartin houses should be placed in an open location, at least 40 ft. from trees or buildings. Martins prefer to have clear access to houses from all sides, and like to have perching sites like utility wires nearby, but not attached to the nest box. The height of the housing can be anywhere from 12-20 ft.
Where are the purple martins 2022?
The Purple Martins officially returned to the PMCA colony sites on April 12th. We spotted two adult males and one female at our West Pier site, two adult males at our Rotary Pavilion site, and one adult male at the Tom Ridge Environmental Center location.

In Texas, they occur primarily east of a line that runs just west of Monahans, Lubbock, FIGURE 2. Purple Martins breed throughout much of North America. [Map courtesy of the Purple Martin Conservation Association.]
How long does it take to attract purple martins?
about 4 to 12 weeksUsually, younger Purple Martins arrive about 4 to 12 weeks after the first adults arrive. In general, your Purple Martin gourds and birds houses can attract Purple Martins well into summer so be sure to not take down your gourd racks or bird houses until late August or early September in northerly areas.
Do purple martins return to the same nest every year?
As long as conditions remain favorable, martins will return year after year to the exact same nesting location. Their range only expands if suitable habitat is no longer available at a previously used site or if new sites or artificial roosts nearby attract younger returning martins.

How to Attract Purple Martins to Your GardenConstruct housing in an open area.Install housing on a telescoping pole.Keep predators at bay.Deter other bird species.Use a little trickery.
Do you have to clean out purple martin houses?
Don't put your martin house up until four to six weeks after the first purple martins arrive. Once purple martins have used a martin house, they will return to it year after year. All you have to do is clean it out in fall, protect it from starlings and sparrows, and perhaps repaint it white every few years.
When do purple martins arrive in Texas?
After spending approximately five months in South America, Purple Martins make their appearance in Texas during the first half of February (Figure 5). Sometimes individuals arrive as early as January. During colder springs, Purple Martins may not appear in northern parts of the Panhandle until late March. The migration of Purple Martins is prolonged, with migrants continuing to arrive at colony sites for 12 to 16 weeks. Males generally arrive before the females of their same age. The oldest Purple Martins (five- to seven-year-olds) generally are the first to arrive. These are followed by the three- to four-year-olds, and then the two-year-olds. Normally, SY Purple Martins do not begin arriving until about five weeks after the earliest ASY martins appear. It is these SY Purple Martins that generally establish new colony sites. Martin landlords often refer to the earliest arrivals in spring as “scouts.” To thousands of landlords, the arrival of the first Purple Martin scout of the season is the sure sign of approaching spring. Contrary to popular belief, the scouts do not return to South America to guide their colony back to the site.
What are purple martins?
The Purple Martin (Progne subis) has been managed intentionally by humans longer than any other North American songbird. For hundreds, perhaps thousands of years, Native American tribes in what is now the southeastern United States hung clusters of hollowed-out gourds to attract this large swallow to their villages (Figure 1). Native Americans may have appreciated the Purple Martins’ beauty, song, or penchant for consuming annoying or depredating flying insects. James R. Hill, III, founder of the Purple Martin Conservation Association, offers the following speculation regarding benefits of Purple Martins that Native Americans may have enjoyed: Perhaps, Purple Martins were like alarm clocks, awakening the village inhabitants with their singing early and regularly each morning. Maybe they served as biological calendars, since every phase of their annual life cycle (from arrival in spring, pairing, nest-building, egg-laying, hatching, fledging and departure) is done on a regular and predictable schedule. They might have been like watchdogs, since they are notorious for giving alarm calls when predators or strangers approach the colony site.
How many cavities do purple martins need?
The minimum number of cavities a landlord should provide for Purple Martins is four, but the more cavities, the better. Multiple cavities are a super stimulus for nest-site-seeking Purple Martins. Many landlords erect one multi-compartment house on a single pole, while others elect to provide cavities among a number of different housing types and on separate poles. It is better to cluster multiple houses (within about 10 feet of each other), as opposed to spreading them all over the property. Housing on separate poles within your yard has the added advantage of providing Purple Martins with choices of nesting habitat relative to specific locations and space within your yard. They may avoid a house for several years but colonize that house immediately following relocation of the house by a mere few feet. Purple Martins readily utilize perches on, and near, martin houses. Some martin enthusiasts attach supplemental perches (dowel rods, etc.) to their housing, or erect “TV antennas” next to or among their martin houses. Nearby TV antennas, utility wires, etc., are always used by Purple Martins for singing, resting, preening, etc. Whether or not the presence of perches will actually attract Purple Martins to use an unestablished site is subject to debate, but martins appear to appreciate them. Purple Martins will use certain materials that are made available to them by the landowner. Crushed eggshells or oyster shells are consumed by martins for calcium and as grit for digestion. Research shows that supplemented calcium — especially from crushed oyster shell — increases the number of eggs laid and the number of young hatched, per clutch. Nesting materials (including mud) can also be offered. These materials can be placed on the ground or on an elevated platform. Persons trying to attract Purple Martins to an unestablished site might find a supply of these materials to be a tool for attracting Purple Martins to their yards from other colony sites. Eventually, some of these visiting Purple Martins might colonize their housing.
What to put in cavities for purple martins?
The Purple Martin and its Management in Texas| 19 It is also a good idea to place wheat straw or pine needles in cavities prior to the spring arrival of martins. Cavities with nesting material may be selected over empty cavities and may provide added insulative protection for early- arriving martins. In addition, this may decrease time spent gathering nesting materials, which keeps birds off the ground and saves energy, thus increasing productivity and survival.
How to stop starlings from nesting in Martin house?
FIGURE 11. The starling-resistant entrance hole, when constructed properly, has been shown to eliminate starlings from trying to nest in martin houses. This diagram shows how to cut a starling-resistant entrance hole for your martin housing. The height dimension is extremely critical. If made even slightly too big, starlings will get in; if made even slightly too small, martins won’t be able to get in. Cut the hole with a jigsaw. Cut it slightly small, then file or sand it to proper height. Also, placement is important. The bottom of the entrance hole may be placed flush with the porch floor, or 1/4" to 1/2" above the porch. It should not be any higher. If cutting the crescent-shaped entrance hole seems too difficult, try the rectangular slot shown. It has also been successful at excluding starlings, while still permitting Purple Martins to enter. Place the slot flush with the porch, or 1/4" to 1/2" above it.
When to open purple martin housing?
The Purple Martin and its Management in Texas| 17 Martin housing should not be erected or opened (unplugged) until one to two weeks prior to the average return dates shown in Figure 5. Erecting housing earlier than that will only result in unnecessary battles with House Sparrows and European Starlings. SY Purple Martins, the only age group that will typically colonize new breeding sites, don’t typically begin arriving until about five weeks after the earliest ASY martins. Consequently, martin housing at unestablished sites need not be made available until four weeks after the average return dates shown in Figure 5. An exception to this rule is that ASY martins can occasionally be lured away from active colony sites less than one mile away if you offer superior housing and/or management, or if they failed to fledge young at another site during the previous nesting season. Prospective landlords that opt to open their housing earlier than the recommended time mustdedicate themselves to frequent and consistent management against House Sparrows and starlings. Martin housing should be taken down or closed up at active colony sites soon after Purple Martins have ended their daily visits following fledging of the young. Martin housing should be left up until late September at unestablished sites; fledgling Purple Martins might investigate housing and “remember” housing the following spring when they return as SY martins. During this time, landlords should remain diligent in managing against House Sparrows and starlings. Martin housing should be erected in open areas at any height between 10 and 20 feet. Highest occupancy rates occur when housing is located at least 40 feet from trees or buildings that are taller than the martin housing. The farther the housing is placed from trees, the better. However, research has shown that martin housing placed morethan 100 feet from human housing (or other areas of high human activity) has a lower chance of being occu- pied. This further illustrates the dependence of Purple Martins on humans east of the Rocky Mountains. A second house should be added to the site when the first becomes one-half full. Pairs generally claim and defend multiple cavities, so rarely is 100 percent occupancy achieved unless cavities do not share a common porch or unless some form of porch dividers are installed.
Where do purple martins nest?
Natural nesting sites of Purple Martins include cavities in trees and tree snags, saguaro and organ pipe cacti, niches in cliff faces, and even on the ground between large boulders. Historically, most nesting probably occurred in woodpecker holes in tree snags (tree hollows), and, as evidenced by today’s western Purple Martins, many may have nested in the hollows of live trees. Tree snag habitat, especially east of the Rocky Mountains, is limited due to susceptibility to weather and fire, suitability for fire wood, and to losses to urban sprawl, “clean farming” and logging. Competition for available cavities occurs among our native cavity-nesting species; however, competition for cavities has been intensified by the intro- duction of the non-native House Sparrow and European Starling. For these reasons, human-provided housing and management has become vital to Purple Martins, especially east of the Rocky Mountains, where they have undergone a complete “tradition shift” and are now the only bird species entirely dependent on humans for supplying them with nesting cavities. Consequently, the purpose of this booklet is to acquaint landowners, home- owners, bird enthusiasts and the general public with Purple Martins and their management needs.

Purple martins feed and roost in large flocks and prey on large aerial insects such as mosquitoes, dragonflies, leaf hoppers, grasshoppers, beetles, and butterflies to name a few. Sometimes you will see a different species of swallows intermingle with purple martins — purple martins will search for their food higher in the air than the other swallows.
Is the purple martin a bird?
The Purple Martin is certainly a unique bird all the way around. Purple martins make for great entertainment with the awesome purple coloring and interesting and spectacular aerial show. However, even though purple martins are a common bird, their species has been on the decline since the 1980’s.
Do purple martins live in protective housing?
Purple martins in Austin have definitely taken a liking to their man-made gourds and specialty birdhouses. This protective housing, usually a gourd of some sort, helps protect purple martins from often brutal and aggressive attacks and hostile takeovers by European Starlings, House Sparrows, and Finches. Purple martins and their nestlings are often overrun and killed by these different species of birds.

Where do Texas martins go?
The route back also had been unclear, but tracking birds tagged originally in Corpus Christ, it’s now been found that some Texas martins follow the coastline of Mexico northward, while others make a gulf crossing - as previously assumed -- leaping northward off the coast of the Yucatan. Also significant, Purple Martins nesting further to the north and west, up into MN, the Dakotas, and Alberta, Canada, all pass through Texas on their trip home.
What is the custom of Purple Martins?
While generations of Americans have hosted Purple Martins - the custom adopted from Native Americans who hung out nesting gourds - specific techniques to help a colony thrive emerged in the past decade, based on research conducted by the PMCA and landlords in the field.

Why do martins starve?
Because martins feed on the wing - taking insects from the air -arrivals during cool periods sometimes face starvation. However, hobbyists have learned to supplemental feed the martins from feeder trays, inside their compartments and sometimes by actually flinging bits of scrambled egg or thawed crickets into the air..
When do martins return to the wild?
New arrivals represent just a trickle of the population and martins continue to return “home” well into spring. The first wave consists of so-called “adult” martins - those two or more years old, with adult males sporting full dark-purple color. Females are a bit drab, with a gray breast. One-year-old martins - called “subadults” -- arrive 10 to 12 weeks later than the older birds - generally into April. These younger birds sometimes are more easily attracted to new housing locations.

Once Purple Martins gather in these roosts they will then break out into smaller groups before leaving to their winter homes in South America.
How long do purple martins live?
Purple Martins can live from five to seven years old. Some have lived as long as ten years. The largest roosting colony of Purple Martins was said to have up to one million birds at a time. Purple Martins catch their food (insects) at heights of one hundred sixty to five hundred feet high.
Why do purple martins leave their nests?
It is that time of year when Purple Martins are leaving their nesting sights to start their pre-migration roosting. This roosting can involve thousands of birds congregating to socialize, feed, and to rest too.
How many broods do purple martins have?
Purple Martins have one brood each year rarely two, unless there was any problems with the first one. When all of this takes place, meaning once the fledglings have left the nest and can fend for themselves, they will join the adults in what is called pre-migration or roosting.
How long does it take for a martin to hatch?
The Martins will then take another four to six weeks until they begin to nest. Incubation of the eggs will take fifteen days when the babies will hatch. Once hatched it will take another twenty six to thirty one days before the babies (nestlings) finally leave or fledge the nest.
Where are purple martins in South Carolina?
Still, in the late summer months, Purple Martins are ubiquitous around South Carolina's Bomb Island. Biologists and birders drift over Lake Murray in their boats to attend the thronging of the birds. This year they were disappointed to find that the birds hadn't turned up.
Where do purple martins migrate?
Purple Martins are among the first birds to return to the States during spring migration. Clumps of martins depart from South America and make their way to the East Coast, where they settle into human-made nest boxes.
What species of birds are responsible for the death of the Purple Martin?
For hundreds of years, humans have provided a safe haven for the martins. But they've contributed to the birds' downfall as well. In the 19th century, the European Starling and the House Sparrow were brought to the U.S., causing Purple Martin populations to suffer dramatically.
Do purple martins need nests?
Purple Martins on the East Coast need man-made nests to survive. When it comes to living in the wild, Purple Martins are out of practice. They've grown so used to birdhouses, they no longer know how to search for nests out in nature.
