Journal Summary of observations (written March 10) Feb. 27 through March 10, 1963 Ojo Laguna, Chihuahua, 5000 ft. el. Mexico Windy and cool to cold most of this period. On two nights the temp. went below 18oF judging from the fact that it was still 18oF when I looked at the thermometer in the morning. There is still not much evidence of spring. Catkins are on cottonwoods and willows but no leaves. Mosquitoes and catclaws still show no signs of life. A few blades of green are showing on Gramma grass or sacaton. Breeding activity. The only birds showing signs of mating are English Sparrows and a few of the Mourning Doves. One dove shot (not preserved) had testes enlarged. A few males have been cooing singly in trees and I have seen a few nuptial flights but most of the are still in flocks. Enlarged gonads were not found in any of the birds prepared. It appears that most of the birds here during this period are resident or winter resident.

Took long walk past ponds near camp and on to the big lake. The big lake (about 2 mi. east of camp & edge of water) is extremely salty. In some places large salt crystals have formed. Also it is very shallow. Birds seen: Green-winged Teal - 15 on pond near camp. Dusky Ducks - 12 on pond near camp. Longspurs, Clark's nuttalled - 100 collected 2. These birds have been present since my first trip to the marsh but I did not record them because I was not certain of identity. The fly in large, compact flocks and are not easily approached. They inhabit the drier grasslands just east of the marshy areas.

Most willows are not. Catclaws & mesquites still dormant. Very little mutual activity among birds and almost no singing. Occasionally we hear a dove cooing, the cooing of a roadrunner or a call from a meadowlark. Birds seen - Very little change from previous recordings. Brewer Sparrows are still here in great numbers. They are in the marsh, in the brush, in dryland grass, on the ground and even high in large cottonwoods. This makes the collecting of other small sparrows difficult. Wilson Sparge still here in usual numbers. Quino? Too far from our pond - one collected.

Journal 26 McBoll Ojo Sajuna, Chihuahua, 5000 ft. el. Mexico. March 16. Returned from Chihuahua at 4 p.m. - did not go to the field Elevation - Jon Christman told me that there was some uncertainty regarding the elevation of this camp. I checked my altimeter on leaving camp and on reaching Chihuahua 1/2 hrs. later. And again on our return, when we left Chihuahua and when we reached camp. Going to Chihuahua our altimeter registered a drop of about 350 feet and on the return a gain of about the same amount. Our A&P basket gives the altitude of Chihuahua as 4593. If we add 350 feet to that we get Ojo Sajuna (altitude) of a prop. 5000 ft. My altimeter seems to be somewhat too much but difficult to read closer than estimated 100 feet. Later notions lead - I believe my altimeter is too much but difficult 16. A, B, Trees in leaf and bird singy in Chihuahua.

Fresh tracks indicated that one raccoon, one shrew (north shore), one skunk ad many ducks, avocet , and curlews had foraged for salamanders, insects ad other food in the rapidly disappearing water. Shorebirds feeding in this extremely shallow water left the marks of their breasts ad toes in the silty mud. These tracks or paths would pass for turtle paths - I saw no evidence of turtles. The raccoon had gone far out into the playa - at least 1/2 mile from the nearest geese cover. Tracks of several salamanders ended abruptly where they were intercepted by the tracks of the raccoon. The surviving salamanders mostly adults were wandering aimlessly over the mud flats or seeking survival in the horsetracks that held water. At my approach their defense was to cower their heads ad raise ad curl their tails. Fortunately for the salamanders last night was cold (38 oF at 7am) ad this morning was extremely foggy.

The last of the fog held on until 11 a.m. Tracks showed that some of the salamanders reached the grassland around the lake and tracks of two led to the (possible?) sockets of rodent burrows. There was no evidence of frogs or turtles or large insect larvae in the playa. Notable by their absence were ococets, curlews, wrenter sandpiper, gulls, blue herons, and shorelers that were present on my last visit to the playa on April 2. Discovery of the salamanders in the playa may account for the previous presence of the blue herons. Among other food items in the salty playa water is a small bivalve. Its presence is indicated by undrows & tiny shells (sample saved).

journal 57 1963 E. Boell Ojosaguna, Chilhuama, 5000 Tol., Mexico. April 19 35° F at 6:30 am. Went to Chilhuama for mail & supplies April 20 in Chilhuama On April 10 I met a Sr. Manuel Ojeda (phone 23064) at the Pemex station corner on Blasiano de los Rios and Universidad. He took me to a taxidermist and guide Alejandro Lopez Escalera, Aldam Pacheco 2205 phone 25097. Mr Ojeda speaks good English, is President of the Apple Growers assoc., has large acres of apples in the mtn. west of Chilhuama and is apparently wealthy. Mr. Ojeda is apparently wealthy, knows the mtn. and state of Chilhuama and offered to assist us whenever needed. To-day (April 20) I again contacted Sr. Lopez with Mrs Baldwin as interpreter. Lopez, who has been (or still is) a professional guide says that he (probably him & his partner) killed 15 grizzlies between 1928 & 1956. In 1954 he killed a ? & captured a cub which he kept in captivity until 1956 when he sold reverse p58

Journal 58 1963 R & Bond Ojo Sayana, Chihuahua, 5000 ft Mexico April 20- continued * to D. Pablo (Buck) Romero, Ford Agency, Mexico City. Lopez believes that this bear is now in the zoo in Mexico City. In 1960 Lopez made a trip into the Sierra del Nido. On that trip he saw the remains of one large bear and two cubs that had apparently been killed by poison. The remains were near the carcass of a dead cow - apparently killed by the grizzlies (and the remains poisoned by the vaqueros). On that trip Lopez says that he saw the tracks of a grizzly that measured 16 inches. Lopez believes that since grizzlies have been protected no professional guides are hunting or taking hunters to hunt grizzlies. However he thinks that ranchers & vaqueros shoot or poison bears as opportunit offers. He claims that vaqueros actually carry poisoned dewet pellets (or balls) when travely in bear country and drop them when bear sign is encountered.

* This is the bear refer to by Charles Leopold on page 420 of his book - wildlife & man.

Journal 1963 E. Borell Ojodaguna, Chihuahua, 5000 ft. Mexico. April 20- Continued. Lopez has photographs of several grizzlies ad black bears (ad wolves) killed in ad around the Sierra del Nido. I obtained from him three 8x10 glossy prints of three of his best photos of grizzlies (100 pesos). Also I obtained from him data on each of the prints. Lopez believes that there are still grizzlies in the Sierra del Nido as well as in surrounding ranges to the north, south ad west. Lopez claims that he knows the mountains ad people of Chihuahua ad is anxious to be employed as a guide if M.V.Z. people want gather more information on grizzlies. Lopez says that formerly there were grizzlies in the Sierra Perico (hills) just north of Chihuahua.

Journal Borell Ojo Sagina, 5200 ft., El. Chihuahua 1964 Mexico (East Bas Sierra del Vado). April 21, 1964 Cresencio Reached the Gutierrez ranch at 6:30 P.M. yesterday. Established camp (house trailer) at the same spot occupied in 1963 (Feb 25 - Apr 25), under the cottonwoods (+) in the yard of Sr. Gutierrez. Today made a trip on foot to some of the better collecting sites north of camp. The area is considerably dryer than at this time last year. Several of the shallow water areas where I collected waterfowl and shortbirds last year are now dry. Someone (within the last week) burned most of the grass area for 1/2 mile north of camp. This burning removed the bullrush and tall grass that formerly surrounded the largest pool. This burning and the dryness greatly deprievated one of the best collecting sites. The big laguna to the east is completely dry. Sr. Gutierrez said they have had a cold, dry, windy, spring. His cattle are extremely poor.

Journal Borel 1964 Ojo Sajuna, Chihuahua, Mex. 5200' el. April 21, 1964 (cont) Cottonwoods are almost in full leaf and the P trees are shedding their cotton, willows are in bloom and just beginning to leaf out. Mesquite are in various stages of leafage, some appear to be dormant others are just beginning to turn green and others are in about 1/4 normal leafage. Grass in the marsh (Sacaton) has green sprouts 4 to 6 inches long. The general appearance of this marsh is still "dead". Among the mesquite there is little evidence of greening of the grass or forbs and the cattle are not foraging among the mesquite as they were at this time last year.

The river bottom between Flores m. and San Lorenzo is irrigated and farmed to maize, cotton and other crops. We were told that this farm land continues up the river for another 10 miles. San Lorenzo is a beautiful spot with many shade and fruit trees, flowers, gardens, irrigation ditches and old adobe houses. Here we met Mr. and Mrs. Jesse Siemens, American missionaries representing the Church of God and Christ. Visiting them were two other missionaries by the name of Peters - both had beards. Mr. and Mrs. Siemens were friendly and cooperative. Mr. Siemens who has been in San Lorenzo for 2 1/2 years, told us that last week he and three Mexican friends saw four deer on the hill across the

Borell 1964 (Ojo Sagura), San Lorenzo, 5000 ftel. Rio Santa Clara Chihuahua Mex. June May 1st. Continued river from San Lorenzo. They got this gun and managed to kill one. It proved to be mule deer spite buck. He said it was large enough to be a real load for four men to carry to the car. He said it was excellent eating, also Mr. Siemens said that last winter (1962-63) the natives of the village killed a black bear in the river bottom near San Lorenzo. Mr. Siemens told us that this river at San Lorenzo flows throughout the year. He said that permanent flow comes from springs near Santa Clara, 40 miles above San Lorenzo. Also he said that following thunder storms in caste summer the Santa Clara flows from bank to bank. Apparently the climate is milder along the Santa Clara than here at least the mesquites appeared to be more nearly in full leaf - but we saw no blossoms.

It is in the center of 4 large cottonwoods and is surrounded by an adobe wall 3-4 ft high. The site is an attraction to birds but I have added with attraction by putting oat meal, toast, fruit sauce, wheat and bird seed. The latter is cheap in Chihuahua. Yesterday I got the idea of putting a brush pile near the water and within good any range of the adobe wall. The brush pile definitely and almost immediately improved the site for collecting birds that formerly drank and left promptly or flew at the slightest disturbance now loiter around the brush pile or take refuge in it when disturbed thus offering an opportunity to collect the desired individuals.

It was a large (4 ft) heavy bodied snake. It was in a little path that leads around one of the ponds. The unusual spot was between a willow and cottonwood with water and sedge on two sides of it and pacators on the other two sides. It was olive grey in color with large diamonds, had two rattles and had just eaten a cotton rat. Last year (1963) by Apr 25 m. Gutierrez had killed two rattlesnakes and I had killed two. The one today is the first that either of us has seen to date this year. Also in a mile walk along a dirt road I encountered the "tracks" of four snakes of unknown identity.

In 1964 (apr.-may) two to three were commonly seen along this same stretch of road. I was not here in 1965. This morning on a trip up and back along this same little of road I counted 10 jacks.

Borell 1966 Ojo Sajuma, Sierra del Indo 5200 ft. Chile, Mex. Apr. 14 Again spent the morning hiking through the mesquite of Cadillan in search of Gambel Quail - to no avail. By noon the temp. had dropped, the wind was blowing and dense clouds were gathering. Between 4 and 5 P.M. we had about 1/2 inch of rain accompanied by thunder and lightning - most unusual to have rain at this season - especially during a period of drought - Mr. Gutierrez (at this camp) was happy. Apr 16- cold, windy and cloudy - took a hike through the mesquite - critters were scarce - nothing new. By 4 P.M. we needed lights in the trailer. Between 5 & 6 P.M. during a thunder and lightning storm we had a small cloudburst - at least an inch of rain, maybe two. Every trail and sully became a small river.

Boell 1966 Ojo Saguna, Siena del rido, 5200 ft. el. Chilacua met Apr 17. Cold windy and partially cloudy day new birds x Belted Kingfisher- new for this location not collected- too wary. Ruby Crowned Kinglet. Apr 18 Cold ad windy 7am. watched repetual flight at dusk. a ♀ quacking loudly and continuously flew in a wide high arc for about 1/2 mile. she was closely pursued by two (silent) birds, apparently males. a fourth bird followed (silent) about 100 feet behind the other three. This is the fourth time I have seen these flights in the six days. In the first instance the ♀ quacking loudly and continuous was followed by only one δ (silent).In two other cases she was followed by 2 ♂s. Two flights were in early morning, two at dusk.*(see p 11)

Boell 1966 Ojocaliente, Sierra del Zinco, 5200 ft el Chihuahua Mex. Apr 18 cont. new birds. Barn owl - one flushed from large cottonwood. Have heard barn owls screech on previous nights. Apr 19 left camp at 7 a.m., headed for Juarez ad home. * About 1/3 as many Diaz ducks present in this area as were here in April 1963. This is likely due to the drought - there is little water except that in the 4 principal ojos. R, E, B.
